Question

How many moles of C2H2 are required to produce 0.39 mol of H2O?

Also,How do I find the mols?

Expert Solution

Step 1

Introduction-

Molarity (M): It is the number of gram moles of solute dissolved per litre of solution. Its SI Unit is moles/litre.

$M = \frac{n}{V}$

n= no. of moles and V=Volume of solution in litres.

$n = \frac{m}{M}$

m= given mass of compound and M= Molar mass of compound

Balanced Chemical equation- When the reactants and products of a chemical reaction becomes equal we call it as a Balanced Chemical equation or reaction.

Example- CH₄ + 4Cl₂ →CCl₄ + 4HCl

Here all the carbon, chlorine and hydrogen atoms are in same number.
