How many grams of H2SO4 are present in 0.500L of a 0.150M H2SO4 solution?

To solve this problem, we need to use the formula:

moles = concentration x volume

We can first calculate the moles of H2SO4 in the solution:

moles = 0.150 mol/L x 0.500 L = 0.075 moles

Then, we can convert the moles to grams using the molar mass of H2SO4:

molar mass of H2SO4 = 98.08 g/mol

grams = moles x molar mass = 0.075 mol x 98.08 g/mol = 7.31 g

Therefore, there are 7.31 grams of H2SO4 present in 0.500L of a 0.150M H2SO4 solution.
