Determine the mass of the salt that forms as a result of the interaction of H2SO4 with NaOH. mass (NaOH) = 20g.

H2SO4 + 2NaOH = 2 H2O + Na2SO4
NaOH to Na2SO4 ratio 2: 1
m NaOH = 20 g
M NaOH = 40 g / mol
n NaOH = 20/40 = 0.5 mol
Then n Na2SO4 0.5 / 2 = 0.25 mol
M Na2SO4 = 142 g / mol
m = 0.25 * 142 = 35.5 g mass of the formed salt
