Answer: [tex]4.994\times 10^{-3}[/tex] moles
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass , 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 mass}}{\text {Molar mass}}[/tex]
Given mass of ethanol = 0.2301
Molar mass of ethanol = 46.07 g/mol
[tex]\text{Number of moles of ethanol}=\frac{0.2301g}{46.07g/mol}=4.994\times 10^{-3}[/tex]
Thus there are [tex]4.994\times 10^{-3}[/tex] moles of ethanol are present in the sample.
