0.5mole
Explanation:
First, we need to calculate the molar mass of K2O. This is illustrated below:
Molar Mass of K2O = (39x2) + 16 = 78 + 16 = 94g/mol
Mass of the K2O from the question = 47.2g
Number of mole of K2O = ?
Number of mole = Mass / Molar Mass
Number of mole of K2O = 47.2/94 = 0.5mole
Therefore, 0.5mole is equal to 47.2g of K2O.

Answer: 0.50 mole K2O
Explanation: To convert the mass of K2O to moles we will need to find the molar mass of K2O.
47.2 g K2O x 1 mole K2O / 94 g K2O
= 0.50 mole K2O
