Answer:
Mass = 25.2 g
Explanation:
Given data:
Number of formula units of NaHCO₃ = 1.8×10²³
Mass in gram = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ formula unit
1.8×10²³formula unit × 1mol / 6.022 × 10²³ formula unit
0.3 mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 0.3 mol × 84 g/mol
Mass = 25.2 g
