Number of moles = 1.57 mol

Explanation:

Given data:

Mass of propanol = 94.1 g

Molar mass of propanol = 60.1 g/mol

Number of moles of propanol = ?

Solution:

Formula:

Number of moles = mass/molar mass

by putting values,

Number of moles = 94.1 g/ 60.1 g/mol

Number of moles = 1.57 mol

1.solid

2.carbon dioxide

3.helium
