Q-13. The formula of Ethanel is "C2h5oh what will be its
molecular masse and find number of Hydrogen atom
in 23 g of etamel​

Answer 1

Answer:

pls mark brainliest

MOLECULAR MASS =  46g

H - atoms = 3

Explanation:

MOLECULAR MASS = [2×12] + [5×1] + [16] + [1]

                                  = 24 + 5 + 16 +1

                                  =  46g

in 23g of ethanol = moles = 23/46

                               moles = 0.5 moles

hence in one mole of ethanol = 6 H-atoms

           in 0.5 mole of ethanol = 6 × 0.5 = 3 H - atoms
