Calcule a massa malar das substâncias a seguir CH⁴, H²SO⁴, HCL...

Olá!:

a ) CH₄ = 12 + 1 × 4 => 16 g/mol

b) H₂SO₄ = 1 × 2 + 32 ×  1 + 16 × 4 => 98 g/mol

c) HCl = 1 × 1 + 35,5 × 1 => 36,5 g/mol

d) NO = 14 + 16 => 30 g/mol

e) C₂H₆O = 12 × 2 + 1 × 6 + 16 × 1 => 46 g/mol

f) HNO₃ = 1 × 1 + 14 × 1 + 16 × 3 => 63 g/mol

g) CaO = 40 × 1 + 16 × 1 => 56 g/mol

Espero ter ajudado!
