What is the molar mass of sodium bicarbonate, in g/mol? Your answer should have the appropriate number of significant figures (u se two decimal places in atomic masses). Only give the numeric value of your answer. Don’t include the units.
2 answers:
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
