Question

A student using a 100mL graduated cylinder that contained 50.00mL of water. Th volume of the water increased to 57.50mL. The density of the object was 7.85 g/cm^2. How many grams did the metal object weigh?

Answer 1

mass=density*volume=7.85*7.50 grams

Answer 2

So would it be

7.85 g/cm^3 x 7.50mL

do you have to convert the mL and the g/ Cm^3?

What unit would the mass be? grams or mL...

Answer 3

ml=cm^3

mass units will be grams.

remember your units go as in algebra...

c/(a/b)=bc/a
so
g/(g/v)=gv/g=v

Answer 4

Thanks!
