How many grams of sodium bicarbonate are in 1.8 x 1023 formula units?NaHCO3 anyone fst please:

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
