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

therefore there’s 3 electrons and 3 protons
