74 g potassium chloride converted to moles

Number of moles = 0.99  mol

Explanation:

Given data:

Mass of potassium chloride = 74 g

Number of moles of potassium chloride = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of KCl = 74.6 g/mol

now we will put the values in formula:

Number of moles = mass/molar mass

Number of moles =  74 g/ 74.6 g/mol

Number of moles = 0.99  mol
