What is the mass of 2.50 moles of potassium chlorate in grams

Sedaia [141]

Answer: 306 grams are there in 2.50 moles of potassium chlorate

Explanation

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

given mass of potassium chlorate = ?

Molar mass of potassium chlorate = 122.55 g/mol

Putting in the values we get:

$2.50=\frac{xg}{122.55g/mol}$

$x=2.50mol\times 122.55g/mol=306g$

306 grams are there in 2.50 moles of potassium chlorate
