Joey · Answer 1

Answer: 83.98g/mol

Explanation:

To calculate the molar mass of sodium bicarbonate, first you must know the atomic mass of different elements present and multiply it by number of moles.

NaHCO3.

Atomic mass of sodium (Na) = 22.99*1

Atomic mass of carbon (C)

12.10 * 1 = 12.10

Atomic mass of oxygen (O)

15.99*3 = 31.98g

Atomic mass of hydrogen is 1.00

Add the atomic mass together.

NaHCO3 = 22.99+12.10 + 1.01+47.97 = 83.98g/mol

Camille Boyer · Answer 2

Answer: 105.96

Explanation:

Sodium bicarbonate (Na2CO3)

Atomic mass of Sodium (Na) = 22.99

Atomic mass of Carbon (C) = 12.01

Atomic mass of oxygen = 15.99

Na2CO3 has a molar mass of (22.99x2) + 12.01 + (15.99x3) which is equal to

45.98 + 12.01 + 47.97 = 105.96

Thus, the molar mass of sodium bicarbonate is 105.96g/mol
