Question

What is the amount in moles of 14.83 g of potassium chloride?

Answer 1

To find the amount in moles of potassium chloride, we first need to determine the molar mass of KCl (potassium chloride).

The molar mass of KCl is calculated as follows:
Potassium (K) = 39.10 g/mol
Chlorine (Cl) = 35.45 g/mol

Molar mass of KCl = 39.10 g/mol + 35.45 g/mol = 74.55 g/mol

Now, we can calculate the amount in moles of 14.83 g of potassium chloride:
Amount in moles = Mass / Molar mass
Amount in moles = 14.83 g / 74.55 g/mol ≈ 0.199 moles

Therefore, the amount in moles of 14.83 g of potassium chloride is approximately 0.199 moles.
