Question
To calculate the number of moles of H2SO4 in 500 ml of a 0.324 M H2SO4 solution, you can use the formula:
moles = concentration (M) × volume (L)
1. First, convert the volume from milliliters to liters:
volume (L) = 500 ml ÷ 1000 = 0.5 L
2. Substitute the values into the formula:
moles = 0.324 M × 0.5 L = 0.162 moles H2SO4
Therefore, there are 0.162 moles of H2SO4 in 500 ml of a 0.324 M H2SO4 solution.
To calculate the number of grams of H2SO4 in the same solution, you need to use the molar mass of H2SO4. The molar mass of H2SO4 is:
2(1.008 g/mol) + 32.06 g/mol + 4(16.00 g/mol) = 98.09 g/mol
1. Multiply the number of moles (0.162 moles) by the molar mass of H2SO4 to calculate the grams of H2SO4:
grams = 0.162 moles × 98.09 g/mol = 15.90 grams H2SO4
Therefore, there are 15.90 grams of H2SO4 in 500 ml of a 0.324 M H2SO4 solution.
To calculate the number of moles of H2SO4 in the given solution, you can use the formula:
moles = concentration (in M) × volume (in L)
Given:
Concentration of H2SO4 solution = 0.324 M
Volume of solution = 500 ml = 0.5 L
Using the formula, substitute the given values and calculate:
moles = 0.324 M × 0.5 L
= 0.162 moles
Therefore, there are 0.162 moles of H2SO4 in 500 ml of 0.324 M H2SO4 solution.
To calculate the number of grams of H2SO4 in the given solution, you can use the formula:
grams = moles × molar mass
The molar mass of H2SO4 is calculated by summing the atomic masses of its elements:
H = 1 g/mol × 2 = 2 g/mol
S = 32 g/mol
O = 16 g/mol × 4 = 64 g/mol
Molar mass of H2SO4 = 2 + 32 + 64 = 98 g/mol
Using the formula, substitute the calculated moles value and molar mass:
grams = 0.162 moles × 98 g/mol
≈ 15.876 grams
Therefore, there are approximately 15.876 grams of H2SO4 in 500 ml of 0.324 M H2SO4 solution.
