PLEASE HELP!!

How many moles are present in 431.56 grams of sodium bicarbonate ( NaHCO3)?

Molar mass of sodium bicarbonate (NaHCO3) = 84.01 g/mol

Answer 1

5.14mole

Step-by-step explanation:

Given parameters:

Mass of sodium bicarbonate = 431.56g

Unknown:

Number of moles = ?

Solution:

To find the number of moles, we use the expression below:

Number of moles =
`(mass)/(molar mass)`

Molar mass = 84.01g/mol

Number of moles =
`(431.56)/(84.01)` = 5.14mole
