Solution N3

How many mL of 2.00 M H2SO4 are required to neutralize 50.0 mL of 1.00 M KOH?

H2SO4 + 2KOH K2SO4 + 2H2O

0.0500 L x 1.00 mole KOH x 1 mole H2SO4 x

1 L 2 mole KOH

1 L x 1000 mL = 12.5 mL

2 mole KOH 1 L

Solution S4

0.040 L x 1.5 mole NaOH x 1 mole H3PO4

1 L 3 mole NaOH

x 1 = 0.80 mol/L = 0.80 M

0.025 L
