If you have 3.23 x 1023 particles of NaOH, how many grams of NaOH are present?

Answer by Guest

The number of grams contained in 3.23 x 10²³ particles of NaOH is 21.6g.

How to calculate mass?

The mass of a substance can be calculated by multiplying the number of moles in that substance by its molar mass as follows:

Mass = no of moles × molar mass

However, the number of moles in 3.23 x 10²³ particles of NaOH compound must first be calculated as follows:

no of moles = 3.23 x 10²³ particles ÷ 6.02 × 10²³

no of moles = 0.54 moles

The mass of NaOH can be calculated as follows:

Molar mass of NaOH = 23 + 16 + 1 = 40g/mol

mass = 0.54 moles × 40g/mol

mass = 21.6g

Therefore, the number of grams contained in 3.23 x 10²³ particles of NaOH is 21.6g.
