QUESTION: Problem 73P
Concentrated sulfuric acid (18.3 M) has a density of 1.84 g/mL.
(a) How many moles of H2SO4 are in each milliliter of solution?
(b) What is the mass % of H2SO4,in the solution?
ANSWER:
Solution 73P
Step 1 of 2
a.
Here, we have to calculate the number of moles of H2SO4 are in each millilitre of solution.
Given
Molarity of the solution = 18.3 mol/L.
Given volume of solution = 1 L.
Write the equality and conversion factor.
1L = 1000ml.
So, the conversion factor is
Molarity =
Rearrange the formula is as follows.
Moles of solute = Molarity of solution volume of solution.
= 18.3 mol/L
= 1.83 x 10-2 mol /ml.
Therefore, number of moles of H2SO4 solute is 1.83 x 10-2 mol/ml.
