The molar mass of ethanol (CH3CH2OH) can be calculated as:
12.01 + 3(1.01) + 2(12.01) + 1(16.00) = 46.07 g/mol
To find the number of moles present in 30.0g of ethanol, we can use the formula:
moles = mass/molar mass
moles = 30.0g/46.07 g/mol
moles = 0.651 mol
Therefore, there are 0.651 moles of ethanol present in 30.0g of ethanol.
how many moles are in 30.0g of ethanol (CH3CH2OH)?
element - molar mass
carbon: 12.01
hydrogen: 1.01
oxygen: 16.00
