Answer 6

Here are the masses of all the elements in the second chemical compound.
potassium | 39.0983 u (unified atomic mass units)
phosphorus | 30.973762 u (unified atomic mass units)
oxygen | 15.9994 u (unified atomic mass units)

Answer 7

From the compound we get, K*3 + P + O*4 = K3PO4 = 39.0983*3 + 30.973762 + 15.9994*4 =212.266262 u. U can be substituted for grams per mole or g/mol.

Answer 8

Does that help?

Answer 9

thats all you do so the answer would be 212.266262
