Question
Hi - I need help with the following questions:
Julie dissolved 20 g of sugar in a cup of water. The mass of the solution was 500 g.
What volume (mL) of water did Julie start with?
How did you determine the starting volume of water?

The density of the pure water she started with is 1.000 g/ml.
Divide water mass (480 g) by density to get volume, which in this case would 480 ml.
That is a very big cup! More like two.. a Starbuck's Grande

Thank you for this information.
Can you give me the formulas involved so I know how you got the answer?
It seems like the water mass was the mass of the solution minus the solute or 500-20 = 480. But how did you get the density of water = 1.000 g/ml?
These formulas would be helpful. Thanks again!
