How would you determine the density of an irregular object? A) d = m/v, so measure the mass of the object using a balance. Then to find volume, fill a with a known amount of water and immerse the object in the water. The amount of dis volume in cm3 or mL. B) It would be impossible to determine the mass of the object without more information. C) d = m/v, so measure the mass of the object using a balance. Then to find volume, meas width, and length using an appropriate measuring tool. What is the SI unit for mass in the metric system? A) g B) mg C) kg What is the SI unit for volume in the metric system? A) mL B) m3 C) L

I'm wondering about question 3

For each kilogram of a​ person's weight, 2.5 milligrams of a drug is to be given. What dosage should be given to a child who weighs 98 ​pounds? Use the fact that 1 lb=0.45 kg.

to the nearest mL). You then gently lower the statue into the water and observe that the volume rises to 682 milliliters. Calculate the density of the statue. Based on Table 2.8, what element might the statue be made of? 96. The average temperature of the human body is 98.6 °F. What is this temperature in °C and K? 98. Which is larger, 1 degree Celsius or 2 degrees Fahrenheit? 100. Convert 400 K to degrees Celsius and degrees Fahrenheit. 02. For new

Dimensional Analysis 5. The mass of a premature baby is usually given in units of grams. If a baby weighs 2070 g, what is the mass in pounds? (1 lb =454 grams)

I need help with my Chemistry problems. Can you help me, please?

12) Perform the following conversions using dimensional analysis and proper set up. Provide each answer with correct units and significant figures in the space provided. Note that you can square a length relationship to obtain an area relationship and you can cube a length relationship to obtain a volume relationship. It may be easier to treat prefixes separately. f) Convert 155 cm? to ft?

Honestly i'm really confused on even where to start? Do I need to use the density formula?

Record the volume of the liquid in the graduated cylinder to the correct number of significant figures.
