Question

A student weighed an empty graduated cylinder and found that it had a mass of 25.23 g. When filled with 25.0 mL of an unknown liquid, the total mass was 50.92 g. What is the density of the liquid?

Answer 1

`rho" (density)"` `=` `"Mass"/"Volume"` `~=` `1*g*mL^-1`

Explanation:

For your problem, `rho=((50.92-25.23)*g)/(25.0*mL)` `=` `1.03*g*mL^-1`

Alternatively `rho=((50.92-25.23)*g)/(25.0xx10^-3L)` `=` `??g*L^-1`
