Answer 1

Answer: Mrs.Buller collects a 500-ml sample of seawater for her chemistry class, and it has 1.94% of chlorine, we have to determine the amount of chlorine in the sample:

$\begin{gathered} C=\frac{1.94}{100}\times500=9.7ml \\ C=9.7ml \end{gathered}$

Therefore the chlorine content in 500ml of water is 9.7ml.
