How do you convert 212.26 grams of potassium phosphate to moles?
yaroslaw [1]

Answer: 1 mol of potassium phosphate.

Explanation:

Find the molar mass of potassium phosphate.

Equation of potassium phosphate = K3PO4

The molar mass of K = 39.10 g/mol, P = 30.97 g/mol, O = 16.00 g/mol (use periodic table for these values).

Then add them up together based off of the equation.

3(39.10 g/mol) + 30.97 g/mol + 4(16.00 g/mol) = 212.27 g/mol

Multiply the 212.26 grams by the molar mass (unit conversion method).

212.26 g*\frac{1 mol}{212.27 g} = 1.00 mol

There is 1 mol of potassium phosphate.
