Mass % workcheck

[Wonch]

The question was:

Suppose you make a solution that contains 11.51 g of sodium chloride and 194 g of water.
(a) What is the mass % of sodium chloride?
(b) If 10.62 mL of your solution weighs 11.028 g,what is the density (in g/cc)?


For (a) I did this:

Mass percent = (11.51/205.51) x 100
= 5.6

For (b) I did this:

D = M / V
D = 11.028g / 10.62mL
D = 1.038 (this is g/mL) --> How can I convert to g/cc or is it the same (1mL = 1cc)?


Is this work correct?

Thanks for reading. :)
