can any one try solving this Chem. Equation?

Question

anonymous · Answer

Calculate the mass/volume percent, %(m/v) for the solute in each of the following solutions:
$$a; 75g of Na _{2} SO _{4} solution$$
b. 39g of sucrose in 355mL of a carbonated drink

anonymous · Answer

ok do you have the amount of solution in part a?

anonymous · Answer

a. All you're given is mass, are you sure they didn't give you a volume?

anonymous · Answer

b. 0.039kg/0.355L - your answer's units will be in kg/L

anonymous · Answer

sorry missed some. 
a. 75g of Na2SO4 in 250 mL of Na2SO4 solution
b. 39g of sucrose in 355 mL of a carbonated drink

anonymous · Answer

$$Na _{2}SO _{4}$$

anonymous · Answer

just do .075kg/.250L=0.3Kg/L*100=30% Na2SO4 solution

anonymous · Answer

So a. will be:

0.075kg/0.250L

again, units will be kg/L. better check what units they want.
