Question
How many moles of H+ are there in 1.980 g of H2SO4?
Give your answer in moles and to three decimal places.
(Molar mass of H2SO4 = 98.08 g mol−1)
Solution
Step 1: Calculate the number of moles of H2SO4
The molar mass of H2SO4 is given as 98.08 g/mol. The number of moles is calculated by dividing the mass of the substance by its molar mass.
So, the number of moles of H2SO4 = mass / molar mass = 1.980 g / 98.08 g/mol = 0.0202 mol
Step 2: Determine the number of moles of H+ in H2SO4
In one molecule of H2SO4, there are 2 atoms of hydrogen. Therefore, in one mole of H2SO4, there are 2 moles of H+.
So, the number of moles of H+ = 2 * number of moles of H2SO4 = 2 * 0.0202 mol = 0.0404 mol
Therefore, there are 0.040 moles of H+ in 1.980 g of H2SO4.
