Question

Calculate the molar mass of NaHCO3. (Round to the nearest
tenth)
g/mol

Answer 1

84 g/mol.

Step-by-step explanation:

Hello,

In this case, for us to compute such mass, we consider the atomic mass of sodium, hydrogen, carbon and oxygen as well as the three as the oxygen's subscript indicating there are three oxygens. Thus, the molar mass results

`M=m_(Na)+m_(H)+m_(C)+*3m_(O)=23g/mol+1g/mol+12g/mol+3*16g/mol\\M=84g/mol`

Best regards.

Answer 2

84.0 g/mol

Step-by-step explanation:

Molar mass of NaHCO₃ = ?

Solution:

Molar mass is the sum of masses of all atom present in formula.

Molar mass of sodium = 23 g/mol

Molar mass of hydrogen = 1.008 g/mol

Molar mass of carbon = 12 g/mol

Molar mas of Oxygen = 16 g/mol

Molar mass of NaHCO₃ = 23 + 1.008 + 12 + 16× 3

Molar mass of NaHCO₃ = 23 + 1.008 + 12 + 48

Molar mass of NaHCO₃ = 84.008 g/mol

To the nearest tenth = 84.0 g/mol
