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.

To calculate the mass of the solution containing 6.50% sodium sulfate by mass, we need to use the percent composition formula. The formula is:
(mass of component / mass of solution) x 100% = percent composition
In this case, the component is sodium sulfate (Na2SO4) with a given mass of 1.50g, and we want to find the mass of the solution.
Let's assume the mass of the solution to be 'x' grams.
According to the formula:
(1.50g / x) x 100% = 6.50%
To solve for 'x', we rearrange the equation:
1.50g / x = 6.50% / 100%
Simplify the percentage:
1.50g / x = 0.065
Cross-multiply:
1.50g * 1 = x * 0.065
x = (1.50g * 1) / 0.065
x ≈ 23.08g
Therefore, the mass of the solution containing 6.50% sodium sulfate by mass is approximately 23.08 grams.
