How many liters of 0.98 M have solution would react completely with 3.5 moles ca (oh) 2

The question is typed wrong. Assuming the correct question is

How many liters of 0.98 M H2SO4 solution would react completely with 3.5 moles Ca (OH) 2?

Answer:-

3.571 litres

Explanation:-

The balanced chemical equation for this reaction is

H2SO4 + Ca (OH) 2 = CaSO4 + 2 H2O

From the balanced chemical equation we see that

1 mole of Ca (OH) 2 reacts with 1 mol of H2SO4.

∴3.5 moles of Ca (OH) 2 reacts with 1 x 3.5 / 1 = 3.5 mol of H2SO4.

Strength of H2SO4 = 0.98 M

Volume of H2SO4 required = Number of moles of H2SO4 / Strength of H2SO4

= 3.5 moles / 0.98 M

= 3.571 litre
