Question

Calcular el peso molecular del H2O, H2SO4, CH4 , CH3-CH3. P.A= C=12 S=32

Answer 1

Respuesta:

H2O= 18 g/mol

H2SO4 = 98 g/mol

CH4 = 16 g/mol

CH3 - CH3 = 30 g/mol

Explicación:

H2O

H = 2*1   = 2

O = 16*1 = 16                    16 +2 = 18 g/mol

H2SO4

H = 1* 2 =2

S =  1*32= 32

O = 4*16= 64                   2+32+64= 98 g/mol

CH4

H= 4 + C= 12 = 16 g/mol

CH3 - CH3

H= 6*1 =6

C= 2*12 = 24                             24+6 = 30 g/mol
