How many moles are in 1.50 grams of ethanol, CH3CH2OH?
CH3CH2OH = 46.068 (molar mass)
1.50g(1 mole / 46.0680) =
0.03256 moles
Answer: The number of moles of ethanol for given amount is 0.0326 moles.
Explanation:
To calculate the number of moles, we use the equation:
\(\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}\)
We are given:
Given mass of ethanol = 1.50 g
Molar mass of ethanol = 46.07 g/mol
Putting values in above equation, we get:
\(\text{Moles of ethanol}=\frac{1.50g}{46.07g/mol}=0.0326mol\)
Hence, the number of moles of ethanol for given amount is 0.0326 moles.
