The number of moles of water present in a spherical water droplet of radius

1.0 \mathrm{~cm}

is

[Given: density of water in the droplet

=1.0 \mathrm{~g}

\left.\mathrm{cm}^{-3}\right]

View answer and explanation

Correct option: B

\frac{2 \pi}{27}

Option B (2π/27) is correct because the number of moles of water is calculated from the volume of the sphere, density of water, and molar mass of water.
