Question

Ch4, c2h6, c2h2 has equal mole then what is its molecular mass in amu

Answer 1

hey mate!!!

molecular mass of CH4 is

molar mass of C is 12

molar mass of H is 1*4= 4

so molar mass of CH4 is = 12+4 = 16

molecular mass of C2H6 is

mass of C is 12 *2 = 24

mass if H is 1*6 = 6

so molar mass of C2H6 is = 24+6 = 30

molecular mass if C2H2 is

molar mass of C is 12*2 = 24

molar mass of H is 1*2 = 2

so molar mass of C2H2 is = 24+2 = 26
