1.97moles

106.7/(1.01x2+16)/3x1 = 1.97

moles of C2H5OH are needed to generate 106.7 g of H2O IS 1.975 g

What is the mole concept?

A mole is simply a number whose price is the same as Avagadro's variety i.e. 6.022 * 1023. 1 mole in quantity,

balancing chemical equation:-

C2H5OH(ℓ) + 3 O2(g) → 2 CO2(g) + 3 H2O(ℓ) balanced

1mole of C2H5OH(ℓ) produces = 3 mole of water

                                                    = 3*18 (mass of 1 mole of water is 18)  

                                                   = 54 g  

54g of h20 needed=1mole of C2H5OH

106.7 g of h20=106.7/54 g

                   = 1.975 g answer
