Vedclass · Answer

(B) The concentration of $H^{+}$ ions in pure water is $10^{-7} \ M$.Number of $H^{+}$ ions in $1 \ L = 10^{-7} 	imes 6.022 	imes 10^{23}$.The concentration of $H_2O$ in $1 \ L$ is $\frac{1000 \ g}{18 \ g/mol} \approx 55.56 \ M$.Number of $H_2O$ molecules in $1 \ L = 55.56 	imes 6.022 	imes 10^{23}$.Ratio = $\frac{10^{-7} 	imes 6.022 	imes 10^{23}}{55.56 	imes 6.022 	imes 10^{23}} = \frac{1}{55.56 	imes 10^7} \approx 1 : 55.6 	imes 10^7$.Given the options provided,the closest value is $1 : 55.4 	imes 10^7$.

What is the ratio of the number of $H^{+}$ ions to the number of $H_2O$ molecules in $1 \ L$ of water?
