Question

Calculate the number of moles of sodium sulphite present in 6.3 g of Sodium sulphite
​

Answer 1

Explanation:

We first write down the molecular formula of Sodium Sulphite . Formula : Na₂SO3 From here , let's calculate the molar mass of Sodium Sulphite . Na = 23 S = 32 O = 16 Molecular mass of the compound is given by : = 23 x 2 + 32 + 16 × 3 = 126 grams per moles Substituting the values we have : Moles = 6.3 / 126 = 0.05 moles . The formula for getting the moles of a substance is given by : Moles = Mass of substance / Molar mass

Answer 2

Answer:

Moles = 6.3/126 = 0.05 moles.
