Answer: 46.08 grams/mol
Explanation:
Molar mass is the amount of mass in grams per one mole of the substance.
The values given in the table are the values of one element in a given chemical formula. For this question we are given that:
Carbon: 12.01
Hydrogen: 1.01
Oxygen: 16.00
These values are the mass per one mole of the element. In this case for the calculations, we would use the number every time we see the element show up. So, for Ethanol (CH3CH2OH), the calculations would be:
((12.01*2)+(1.01*6)+16) = 46.08 grams
This number would be the molar mass of ethanol, since it combines the molar masses of the elements. To find the molar mass of a compound and substance, you add up the molar mass of the elements.
