Question

question 1
what is the molar mass of scpo4? (give the answer in g/mol. no spaces)

Explanation:

Step1: Find molar mass of each element

Molar mass of Sc (\(M_{Sc}\)) = 44.96 g/mol, P (\(M_{P}\)) = 30.97 g/mol, O (\(M_{O}\)) = 16.00 g/mol.

Step2: Calculate molar mass of \(ScPO_{4}\)

\(M = M_{Sc}+M_{P}+4\times M_{O}\)
\(M=44.96 + 30.97+4\times16.00\)
\(M=44.96+30.97 + 64.00\)
\(M = 139.93\) g/mol

Answer:

139.93
