Question

Calculate the mass of one mole of NaHCo3

Answer 1

Explanation:

formula of mole= mass/molecular mass

so here molecular mass of NaHCO3 will be 84g as

Na=23g, H=1g, C=12g and O=3×16=48g......

so when you add them you will get 84 g

so by formula we can say

1 = mass/84g

or, mass = 84g

So one mole of NaHCO3 has mass of 84g....
