Anyone good at chemistry?

A sugar solution contains 15%sugar(C12H22O11) by mass and has a density of 1.06g/mL
How many grams of sugar are in 1L of this solution...I got 159g/L
What is the molality of this solution? (molality is moles solute/Kg of solvent)
anyone know?
I got the molarity as .465mol/L if that helps....

Wow, talk about off topic.

Yes.

1000 ml at 1.06gmg-1 = 1060 grams. 15% by weight so 0.15 x 1060 = 159g of sugar

RMM of sugar = (12 x 12)+(11 x 16) + (22 x 1) = 342

number of males = mass/RMM = 159/342 = 0.4649 moles per litre

congratulations. You can do chemistry +10% to research.
