Question

Find the no of atoms in a mixture of 0.5mole of Sodium hydroxide and 0.2 mole of calcium hydroxide​

Answer 1

Answer:

A. Find the no of atoms in a mixture of 0.5mole of Sodium hydroxide and 0.2 mole of calcium hydroxide ?

Ans :- H2SO4+Ca(OH)2→CaSO4+2H2O

1 mole of sulphuric acid reacts with 1 mole of calcium hydroxide to form 1 mole calcium sulphate.

We have 0.5 moles of H2SO4 and 0.2 moles of Ca(OH)2. 

Hence, Calcium hydroxide is limiting here, so 0.2 moles of CaSO4 will be produced.
