Hello a compound with:

density of: .80 g/cm^(3)
volume of: 1ML
what is the mass?
How do you conver this?

mass = volume x density
solve for mass
volume = 1 mL = 1 cc = 1 cm^3
density = 0.8 g/cc
plug and chug
Post your work if you don't understand this and tell us exactly what it is you don't understand.

I got .8 grams for mass because I multiplied 1mL=1cm^(3) and the density which is .8 (g/cc)

That't right.
mass = v x d
mass = 1 cc x 0.8 g/cc = 0.8 g = 800 mg.

To convert the density from grams per cubic centimeter (g/cm^3) to grams per milliliter (g/mL), you need to know that 1 gram is equal to 1 cubic centimeter (cc). Therefore, 1 g/cm^3 is equivalent to 1 g/mL.

To calculate the mass, you can use the formula:

mass = volume x density

Given that the volume is 1 mL and the density is 0.8 g/cm^3, you can substitute these values into the formula:

mass = 1 mL x 0.8 g/cm^3

Since 1 mL is equivalent to 1 cc, you can rewrite the equation as:

mass = 1 cc x 0.8 g/cm^3

By multiplying 1 cc by 0.8 g/cm^3, you get:

mass = 0.8 g

Therefore, the mass of the compound is 0.8 grams. Additionally, you can convert the mass to milligrams (mg) by multiplying by 1000 since there are 1000 milligrams in a gram:

mass = 0.8 g x 1000 mg/g

This gives you:

mass = 800 mg

So, the mass of the compound is 0.8 grams or 800 milligrams.
