Answer: Thus there are 0.0870 moles of water sample.
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given molecules}}{\text {avogadro's number}}[/tex]
[tex]\text{Number of moles of water}=\frac{5.24\times 10^{22}}{6.023\times 10^{23}}=0.0870moles[/tex]
Thus there are 0.0870 moles of water sample.
