Question

If 20.0 g H2SO4 is dissolved to make 250.0 mL of a solution, what is the molarity of this solution?

Answer 1

To find the molarity of a solution, use the formula Molarity (M) = moles of solute / volume of solution (in liters). Convert grams to moles and milliliters to liters before substituting the values into the formula.

Step-by-step explanation:

To find the molarity of a solution, we need to use the formula:

Molarity (M) = moles of solute / volume of solution (in liters)

In this case, we have 20.0 g of H2SO4 and a volume of 250.0 mL (or 0.250 L) of a solution. We first need to convert grams of H2SO4 to moles:

Moles of H2SO4 = mass of H2SO4 / molar mass of H2SO4

Next, we can substitute the values into the formula to calculate the molarity:

Molarity = moles of H2SO4 / volume of solution

Remember to convert grams to moles and milliliters to liters to get the correct answer.
