1. 135.0ml to grams

- Math? -
**Damon**, Friday, March 22, 2013 at 2:11pmOne, ml, is a measure of volume.

However grams is a measure of mass.

There is no conversion any more than between meters and grams.

If you assume some density, such as that of water, then you can do it.

For example if water has a density of 10^3 kg/m^3

and a liter is .001 or 10^-3 m^3

then a ml is 10^-6 m^3

so

(10^-6 m^3/ml)(10^3kg/m^3))(10^3 g/kg)

= 1 g/ml

by the way a ml is a cubic centimeter, cc

**Unknown**, Friday, March 22, 2013 at 2:25pmOkay.

This is the question:

If 130.943 g of a liquid occupy a space of 135.0 ml, what is the density of the liquid in g/cm3?

And this is my answer: 0.9699481g/ml

481 is repeating

**Steve**, Friday, March 22, 2013 at 3:28pmNow you are correct.

Except they wanted the answer in g/cm^3.

Even though 1ml = 1cm^3, answer the question as asked.
