We are required to calculate the molar mass of
Given the molar mass of Ec = 31.79 g/mol
We know from the periodic table of elements that the molar mass of:
H = 1,00784 g/mol
O = 15.999 g/mol
To get the molar mass of Ec2H1O1:
We will add the molar masses of Ec + H + O
=> (31.79 x 2) + 1.00784 + 15.999
=> 80.587 g/mol
Therefore the molar mass of Ec2H1O1 = 80.587 g/mol
