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).
= 1.00 mol
There is 1 mol of potassium phosphate.
