The mass of a substance is the product of the moles and the molar mass of the compound.
Mass (m) = Moles (n) × Molar mass (M)
The mass of 2.5 moles of Potassium chlorate will be 306.37 g.
This can be calculated by:
Given,
M= 39.0983 + 35.453 + (15.999) 3
= 122.5483 g/mol
Mass (m)= nM
= 2.5 × 122.5483
= 306.37 g
Therefore, the mass of 2.5 moles of potassium chlorate (KClO₃) is
306.37 g.
