How many moles are equal to 47.2 g of K2O

The number of moles is 0.5 moles

The first step is to calculate the molar mass

K20

= 39×2 + 16

= 78 + 16

= 94 g

Number of moles= mass/molar mass

= 47.2/94

= 0.5

Hence the number of moles is 0.5 moles

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.

explanation:

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
