Question

What mass of solution containing 6.50% sodium sulfate N2SO4 by mass contains 1.50g Na2SO4

Set up a proportion.
(g Na2SO4/g solution) = (1.50 g Na2SO4/x g solution).
Solve for x. Check my work.

how do you fine g solution

Answer 1

6.5 g Na2SO4 per 100 g solution.
6.5 goes on top, 100 goes on bottom.

Answer 2

so for this part
(g Na2SO4/g solution) = (1.50 g Na2SO4/x g solution).
it would be (g Na2SO4/ .065 g solution = 1.50 g Na2SO4/ x .065 g solution ) or did i miss place them

Answer 3

No.
It would be (6.5/100) = (1.50/x g solution)

Then cross multiply to obtain,
6.5*x = 100*1.5
x = ??

Answer 4

23.0769 right

Answer 5

The digits are right. I would round it to 23 since you have only two significant digits in the 6.5%. But 23 what? grams. mL. ounces. pounds.
