The volume occupied by one molecule of water (density = 1 `gcm^(-3)`)

Options

A. `3xx10^(-23) cm^(3)`
B. `5.5xx10^(-23) cm^(3)`
C. `9xx10^(-23) cm^(3)`
D. `6.02xx10^(-23) cm^(3)`

Answer

A

Explanation

Mass of one molecule `=(18)/(6.02xx10^(23)) g`
Volume of one molecule `(M)/("Density")=(2.98xx10^(-23))/(1) cm^(3)=3xx10^(-23) cm^(3)`.
