Chapter 1, Problem 1.53E

Interpretation Introduction

Interpretation:

The number of hydrogen molecules in $2.0\text{g}$ of hydrogen gas is to be expressed without using scientific notation.

Concept introduction:

Scientific notation is used to write large numbers or small numbers as the product of a non-exponential term and exponential term in the form of $M\times {10}^n$. The $M$ is any number between $1$ to $10$ written with a decimal after first non-zero digit in the number and $n$ is the exponent which may be positive or negative.
