- What is the difference between (a) mass and density? (b) an extensive and an intensive property? (c) a solvent and a solution?arrow_forwardThe density of a solution of sulfuric acid is 1.285 g/cm3, and it is 38.08% acid by mass. Calculate the volume of the acid solution (in mL) you need to supply 125 g of sulfuric acid.arrow_forwardA solution is prepared by dissolving table salt, sodium chloride, in water at room temperature. a Assuming there is no significant change in the volume of water during the preparation of the solution, how would the density of the solution compare to that of pure water? b If you were to boil the solution for several minutes and then allow it to cool to room temperature, how would the density of the solution compare to the density in part a? c If you took the solution prepared in part a and added more water, how would this affect the density of the solution?arrow_forward
- You are on a road trip. Your car travels at an average speed of 65 miles/hr, with an average gas use of 17.8 km/L. 1 liter = 1,000 mL = 0.264 gallons. 1 km = 0.621 miles. 1) If your trip takes 2.6 hours, determine how many total liters and gallons of gasoline are used on this trip. 2) How many mL (milliliters) of gasoline are used by the car each minute during this trip? 3) The density of the gasoline used on your trip is 0.755 g/mL. What is the total mass in grams, and in ounces of the gasoline used on your trip?arrow_forwardNurses are often required to calculate dosages. That is, they must check the order that a doctor has given for the administration of a drug and decide whether the dosage is correct. To calculate correctly they must convert between different metric units. For example, 1,000 milligrams (mg) = 1 gram (g); and 1,000 micrograms (mcg) = 1 mg. - Suppose a doctor has ordered a dose of 0.1 gram of a medication. The drug comes in a solution concentration of 300 mg per milliliter. How many milliliters of this solution is required?arrow_forwardNurses are often required to calculate dosages.

The drug comes in a solution concentration of 300 mg per milliliter. How many milliliters of this solution is required? - Now, calculate how many milliliters you would need to administer 250 mg from a dosage concentration of 1 g per 3 mLarrow_forward
- The density of calcium is given as a rate of 1.55g/mL. What is the density of calcium in pounds per liter if 1lb=0.454kg? Express your answer as a fraction in lowest terms.arrow_forwardWhat is the total mass accumulated in a beaker by successive additions of solids in the amounts 45.65 mg, 8.38 g, and 56840.5 g. Report your answer in grams, g and to the correct number of significant figures. Given: 1 g = 106 g; 1 g = 1000 mgarrow_forwardVanillin (used to flavour vanilla ice cream and other foods) is the substance whose aroma the human nose detects in the smallest amount. The threshold limit is 2.0 x 10-11 g per liter of air. If the current price of 50g of vanillin is $112, determine the cost to supply a large aircraft hangar with a volume of 5.0 x 107 ft3. (1 cm3 = 0.001 L) (1 ft = 30.48 cm)arrow_forward
- Use dimensional analysis to convert the volume for the English measurements of tablespoon and teaspoon to milliters giving your answers to two significant figures. How do these calculated values compare to the ones obtained in the experiment? (1 liquid oz = 29.57 mL; 1 cup = 8 liquid oz; 1 cup = 16 Tbsp.; 1 Tbsp. = 3 tsp.) English Measure Measured Volume in Milliliters (from the Test Data) Calculated Volume in Milliliters 1 Tablespoon (Tbs) 15 ml 1 Teaspoon (tsp) 5 ml show all work with units using dimensional analysisarrow_forwardThe average adult heart pumps about 84./mLs of blood at 72 beats per minute. Suppose you need to calculate how long it would take the average heart to circulate 3600.mL of blood. Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols.arrow_forwardTums is a popular remedy for acid indigestion. A typical Tums tablet contains calcium carbonate mixed with inert substances. When ingested, it reacts with stomach acids (hydrochloric acid) to produce carbon dioxide gas. When a 1.201 g Tums tablet reacted with 42.035 mL of hydrochloric acid (density: 1.140 g/mL), carbon dioxide gas was produced and the resulting solution weighed 48.941 g. Calculate the mass of carbon dioxide gas released. Calculate the volume of carbon dioxide gas released. The density of carbon dioxide is 1.18 g/Larrow_forward
