Question

calculate the molar mass of HNO3 , Na2SO3​

Answer 1

Molar mass of HNO3 =

H + N + 3 (O)

= 1 + 14 + 3 (16)

= 1 + 14 + 48

= 63 g/mol

Molar mass of Na2SO3 =

2 (Na) + (S) + 3(O)

= 2 (21) + 32 + 3 (16)

= 42 + 32 + 48

= 122 g/mol

Hope it helps.

Answer 2

Answer:

63u and 126u respectively

Explanation:

HNO3 = 1*1 + 1*14 + 3*16

= 1 + 14 + 48

= 63u

Na2SO3 = 2*23 + 1*32 + 3*16

= 46 + 32 + 48

= 126u
