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

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
