Question

. Calculate the number of moles present in 250g of Ethanol?

Answer 1

Answer:

The number of moles of Ethanol is 5.4347 moles

Explanation:

The mass of ethanol given is m = 250 g

The molar mass (M) of ethanol (C2H5OH) =2(12)+5(1)+1(16)+1(1)

=46 g/mol

The number of moles can be calculated as follows:

moles= mass/ molar mass

= m/M

= 250 g/ 46 g/mol

= 5.4347 moles
