Question

For a science experiment, Wandalyn needs a

saltwater solution that has a ratio of 31.2 grams of salt
for every liter of water. If Wandalyn uses 37.1 grams
of salt, how much water will she need for her solution?
A 0.001 L
B 0.841 L
C 1.189 L
D 1,157.52 L

Answer 1

To find the amount of water Wandalyn needs for her solution, we need to divide the amount of salt she uses by the ratio of salt to water in the solution. We are given that the ratio of salt to water is 31.2 grams of salt per liter of water, and that Wandalyn uses 37.1 grams of salt. We can write the following equation to represent the amount of water she needs:

Water = (37.1 g of salt) / (31.2 g of salt / 1 L of water)

Solving for the amount of water, we get:

Water = 1.189 L

Therefore, Wandalyn will need 1.189 liters of water to make her saltwater solution. The correct answer is therefore C: 1.189 L.
