D)0.96 g
E)8 g

Question

Quizplus · Accepted Answer

To find the mass of the solution needed, we can use the formula:

mass of solution = mass of solute / percent by mass of solute

Plugging in the given values, we get:

mass of solution = 8 g / 0.12 = 66.67 g

Rounding up to two significant figures, the answer is:

mass of solution = 67 g

Therefore, the best choice is (C).
