Question

what is the molar mass of this compound? liclo₄ remember to round to the hundredths place from the periodic table. 106.39 g/mol 3,936.37 g/mol 58.39 g/mol 15,475.47 g/mol

Explanation:

Step1: Find molar masses of elements

From periodic table: \(M_{Li}=6.94\ g/mol\), \(M_{Cl}=35.45\ g/mol\), \(M_{O}=16.00\ g/mol\)

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

\(M = M_{Li}+M_{Cl}+4\times M_{O}\)
\(M=6.94 + 35.45+4\times16.00\)
\(M=6.94 + 35.45 + 64.00\)
\(M = 106.39\ g/mol\)

Answer:

106.39 g/mol
