Chapter 13, Problem 116E

Interpretation Introduction

Interpretation:

The minimum amount of $1.85M$$HCl$ that is required to produce $28.5L$ of $H_2$ at STP is to be calculated.

Concept introduction:

Molarity is the ratio of the number of moles of solute per liter of solution.

Mathematically, molarity $\left(\text{M}\right)$ will be as follows:

$\text{M=}\frac{\text{Moles solute}}{\text{Liters solution}}$ …… (1)

The volume of solution should be in liters.

Liters to moles conversion: $\frac{\text{moles of solute}}{\text{ L solution}}$

Moles to liters conversion: $\frac{\text{L solution}}{\text{moles of solute}}$

Mole to mole conversion: $\frac{\text{number of moles of A}}{\text{number of moles of B}}$
