Question

what is molecular mass of C2H5-OH

Answer 1

hey there!

molecular mass of C2H5-OH is 46.07 g/mol.

hope it helps!

Answer 2

Hello frnd @Siddharth9032

To know the Molecular mass of a compound........u must know the atomic mass of elements

Atomic mass of one carbon=12, one Hydrogen=1 and one Oxygen=16

So here in C₂H₅-OH, 2 carbon, 6 hydrogen and 1 oxygen are present

• Atomic mass of 2 carbon(C)=2×12=24
• Atomic mass of 6 hydrogen(H)=6×1=6
• Atomic mass of oxygen(O)=1×16=16

Hence molecular mass of C₂H₅-OH

=Atomic mass of 2 carbon(C)+Atomic mass of 6 hydrogen(H)+Atomic mass of oxygen(O)

=24+6+16=46

Hope it will  help u to get ur ans.
