Question

calcula la masa mulecular del nitrato de calcio , Ca (NO↓3)↓2? ayúdenme porfa...​

Answer 1

Respuesta:

1. Masa molar del nitrato de calcio, Ca (NO3)2

Ca: 1* 40.1 g/mol = 40.1 g/mol

N: 2* 14.0 g/mol = 28.0 g/mol

0:2*3*16.0 g/mol = 96 g/mol

Masa molar = 40.1 g/mol + 28.0 g/mol + 96 g/mol = 164.1 g/mol

espero te sirva!
