Which of the following is the number of moles that are present in 150L of water?

The number of moles present in $150$L of water is $8333.3$
As we know,
The density of water is $1000$g/litre, and given volume of water 
$\Rightarrow 150$L
So, the mass of water used in 
$\Rightarrow$ Mass = Volume × Density
$\Rightarrow \mathit{ m}=150 \times 1000$
$\Rightarrow 150000$g
So, the number of moles in $150$L of water 
$\Rightarrow$ mass of water/mass of 1mole of water
 $\Rightarrow \frac{150000}{18}$ moles
$\Rightarrow 8333.3$ moles
