Question

calculate the molecular mass of the following in u. c.c2H5oh​

Answer 1

C2H5OH=2(14)u+5(1)u+16u+1u=28u+5u+16u+1u=50u

Answer 2

Answer:

The Molecular mass of C2H5OH is 46

Explanation:

C stands for Carbon,

H stands for Hydrogen,

O stands for Oxygen

The molecular mass of C=12

Therefore for C2:-

$12 \times 2 = 24$

The molecular mass of H=1

Therefore for H5:-

$1 \times 5 = 5$

Also the molecular mass of O=16 and of H=1

Therefore by adding all the Molecular mass we get,

C2H5OH=24+5+16+1

C2H5OH=46a.m.u.
