- 2. Carry out the following operations and express the answer with the appropriate number of significant figures and units: (a) (5.231 mm)(6.1 mm), (b) 72.3 g/1.5 mL, (c) 12.21 g+0.0132 g, and (d) 31.03 g+ 12 mg.arrow_forwardCarry out the following conversions: (a) 32.4 yd to centimeters, (b) 3.0 × 1010 cm/s to ft/s, (c) 1.42 light-years to miles (a light-year is an astronomical measure of distance—the distance traveled by light in a year, or365 days; the speed of light is 3.00 × 108m/s).arrow_forwardThe volume of water in large scale reservoirs is often measured in units of an acre-foot, which is the amount of water covering one acre of surface to a depth of one foot. An acre-foot is equivalent to 43,560 ft³. A particular water tower in town was constructed to hold 2.95 acre-feet of water. What is the volume of water in liters that the water tower will hold? ( 1 US liquid gallon = 231 cubic inches, 3.785 liters = 1 US liquid gallon)arrow_forward
- 8. Carry out the following conversions: (a) 1.42 lightyears to miles (a light-year is an astronomical measure of distance—the distance traveled by light in a year, or 365 days; the speed of light is 3.00x108 m/s), (b) 32.4 yd to centimeters, (c) 3.0 3x1010 cm/s to ft/s. With solutionarrow_forwardThe density of lithium is 0.530 g/cm^3 what is the volume occupied by 1.20 x 10^3 g oflithium?arrow_forwardThe quantitative significance of “take a deep breath" varies, of course, with the individual. When one person did so, she found that she inhaled 3.62x10^22 molecules of the mixture of mostly nitrogen and oxygen we call air. Assuming this mixture has an average molar mass of 29.0 g/mol, what is her apparent lung capacity in grams of airarrow_forward
- Determine the number of significant figures in the following measurements: (a) 443 cm, (b) 15.03 g, (c) 0.0356 kg, (d) 3.000 × 10–7L, (e) 50 mL, (f) 0.9550 m.arrow_forwardA group of students took turns using a laboratory balanceto weigh the water contained in a beaker. The results theyreported were 111.42 g, 111.67 g, 111.21 g, 135.64 g,111.02 g, 111.29 g, and 111.42 g.(a) Should any of the data be excluded before the average is calculated?(b) From the remaining measurements, calculate the average value of the mass of the water in the beaker.(c) Calculate the standard deviation s and, from it, the 95% confidence limit.arrow_forward) The total amount of fresh water on earth is estimated to be 3.73 x 108 km3. What is this volume in cubic meters? In liters?arrow_forward
- 5) A student correctly determines that 17.1 grams of sucrose are needed to make 50 ml of a 1M solution of sucrose. When making this solution in the lab, the student measured 50.0 ml of water in a measuring cylinder and added that to a beaker. Then the student massed 17.1 grams of sucrose and added it to that beaker. She then mixed the solution well and poured the resulting solution into a graduated cylinder. To her utter shock, the volume of the solution was now 62.0 mL. Explain what happened. Describe the steps the student should have taken to prepare a 50.0 ml solution of 1M sucrose. 6) What volume of 0.10 M solution can be prepared using 11.6 g of NaCl?arrow_forwardA student needs to determine density of a liquid. The student determines mass of an empty.flask to be 251.21 g and then adds 224 mL of liquid to it. The mass of the flask with liquid is 451.13 g. What is the density of the solution in units of g/mL?arrow_forwardDimensional Analysis is a way of doing numerical "book-keeping" when converting quantities or performing calculations. • When converting quantities from one unit to another, conversion factors are used. Solving with Dimensional Analysis and Multiple Units: If I am in Canada where the price of gas is $1.022 USD·L1, how much will it cost me to fill up my gas tank if I travelled 125 km? • Let's also assume that my car gets an average of 30.0 miles/gallon.arrow_forward
