Question

determine the molar mass of nano3. provide an answer to two decimal places.

Explanation:

Step1: <Molar mass formula>

The molar mass of a compound \(M\) is calculated by summing the molar masses of its constituent elements. The formula is \(M=\sum (n_i\times M_i)\), where \(n_i\) is the number of atoms of element \(i\) and \(M_i\) is the molar mass of element \(i\).
For \(NaNO_3\), we have:

• Sodium (\(Na\)): \(n_{Na} = 1\), \(M_{Na}=22.99\space g/mol\)
• Nitrogen (\(N\)): \(n_{N}=1\), \(M_{N} = 14.01\space g/mol\)
• Oxygen (\(O\)): \(n_{O}=3\), \(M_{O}=16.00\space g/mol\)

Step2: <Calculate molar mass>
