Question

Hi, I'm calculating volume of an irregularly shaped solid in my Chemistry class. I'm trying to figure out what unit the solution should be in. Here's my data:

Instructions: Calculate the volume of the irregular-shaped solid for each trial. (Subtract the volume of the water from the total volume of the water and solid.)
50.5 mL – 41.852 g
Would the solution (8.6) be g/mL, mL/g, or...? I thought the unit of volume is usually cm^3 or whatnot, but that doesn't make any sense in this problem. Please explain :)

Answer 1

i think g/ML not sure.

Answer 2

@FluffehPandas help? :)

Answer 3

A volume must be measured in a unit of volume such as liter, milliliter, cubic centimeter, etc.
You have a solid with a measurement in grams. That is not a volume. That is a mass. You can's add or subtract milliliters and grams.

Answer 4

Never mind, figured out that g/mL is a measurement of volume, so I was right. :)

Answer 5

Later in the worksheet, we convert it into a volume. I don't fully understand the units here, but that's what they're having me do. Thanks, @mathstudent55 :)

Answer 6

g/mL is not a unit of volume. It is a unit of density.

Answer 7

Is 41.852 g the mass of the water? If so, you can find the volume of the water by using the density of water. Then you'll have the volume of water also in mL. Then you can subtract the volume of water in mL from the volume of the solid plus water all in mL to find the volume of the solid in mL.
