Question

Taking into account, the rules of significant figures, what is the value of $(436.32\text{g}+0.301\text{g}+227.2\text{g})$?

• A. $663.82\text{g}$
• B. $663.8\text{g}$
• C. $663.821\text{g}$
• D. $664\text{g}$

Answer 1

The correct option is B $663.8\text{g}$

The least precise measurement i.e $227.2\text{g}$ is correct only to one decimal place. So, final result of addition should be rounded off to $663.8\text{g}$.
