Question

A student adds 5 grams of sugar to 1 liter of water one sugar solution. Then, they add 10 grams of sugar to 1 liter of water to make another sugar solution. Which statement correctly compares these solutions?

Answer 1

To compare the two measurements, the quantity we must use is the Molarity, M₂> M₁

Step-by-step explanation:

To compare the two measurements, the quantity we must use is the Molarity, which is defined by the ratio of the mass of solute to the volume of the solvent.

M = n / V

In this case for the first concentration it is

M₁ = 5 10-3 / 1

M₁ = 0.005 M

For the second concentration we have

M₂ = 0.010 / 1

M₂ = 0.010 M

Therefore, the molarity of the second concentration is greater than the molarity of the first

M₂> M₁
