Question

the molar mass of water (h₂o) is approximately g/mol.

Explanation:

Step1: Find the molar mass of hydrogen

The molar mass of hydrogen (\(H\)) is approximately \(1\space g/mol\). Since there are \(2\) hydrogen atoms in \(H_2O\), the total mass contributed by hydrogen is \(2\times1 = 2\space g/mol\).

Step2: Find the molar mass of oxygen

The molar mass of oxygen (\(O\)) is approximately \(16\space g/mol\). There is \(1\) oxygen atom in \(H_2O\), so the mass contributed by oxygen is \(1\times16=16\space g/mol\).

Step3: Calculate the molar mass of \(H_2O\)

Add the masses from hydrogen and oxygen: \(2 + 16=18\space g/mol\).

Answer:

\(18\)
