Use the table of molar masses to complete the question. Do NOT use any other values except the ones provided in the table below.
Element Molar Mass (g/mol)
carbon 12.01
hydrogen 1.01
oxygen 16.00
Using only the molar mass values provided in the table above, correctly calculate the molar mass of Ethanol ( CH3CH2OH
) and type in the value below. (Your answer should be a number with 2 decimal places; i.e. the hundredths place).
The molar mass of Ethanol (CH3CH2OH) can be calculated by adding up the molar masses of each element involved:
Molar mass of carbon (C): 12.01 g/mol
Molar mass of hydrogen (H): 1.01 g/mol
Molar mass of oxygen (O): 16.00 g/mol
( 1 carbon * 2 ) + ( 3 hydrogen * 6 ) + ( 1 oxygen * 1 ) = 24.02 + 6.06 + 16.00 = 46.08 g/mol
Therefore, the molar mass of Ethanol (CH3CH2OH) is 46.08 g/mol.
