Question

now you try some on your own!

1. what would the molar mass of h₂o be?
2. what would the molar mass of sodium chloride be?
3. what would the molar mass of silver chlorate be?

Explanation:

Step1: Find molar mass of \(H_2O\)

Molar mass of \(H = 1\space g/mol\), molar mass of \(O=16\space g/mol\).
For \(H_2O\), \(M = 2\times1+16\)

Step2: Calculate

\(M = 2 + 16=18\space g/mol\)

Step3: Find molar mass of \(NaCl\)

Molar mass of \(Na = 23\space g/mol\), molar mass of \(Cl = 35.5\space g/mol\).
\(M=23 + 35.5\)

Step4: Calculate

\(M = 58.5\space g/mol\)

Step5: Find molar mass of \(AgClO_3\)

Molar mass of \(Ag=108\space g/mol\), molar mass of \(Cl = 35.5\space g/mol\), molar mass of \(O = 16\space g/mol\).
\(M=108+35.5 + 3\times16\)

Step6: Calculate

\(M=108+35.5+48 = 191.5\space g/mol\)

Answer:

1. \(18\space g/mol\)
2. \(58.5\space g/mol\)
3. \(191.5\space g/mol\)
