2. Calculate the number of moles in 65.5 grams of the following: a) Copper (II) Sulfate
b) Magnesium Nitrate
c) Potassium Carbonate

a) Number of moles = 0.41 mol

b) Number of moles = 0.44 mol

c) Number of moles = 0.47 mol

Explanation:

a)

Given data:

Mass of copper sulfate = 65.5 g

Number of moles = ?

Solution:

Number of moles = mass/molar mass

Molar mass of copper sulfate = 159.6 g/mol

Number of moles = 65.5 g/ 159.6 g/mol

Number of moles = 0.41 mol

b)

Given data:

Mass of magnesium nitrate  = 65.5 g

Number of moles = ?

Solution:

Number of moles = mass/molar mass

Molar mass of magnesium nitrate = 148.3 g/mol

Number of moles = 65.5 g/148.3g/mol

Number of moles = 0.44 mol

c)

Given data:

Mass of potassium carbonate  = 65.5 g

Number of moles = ?

Solution:

Number of moles = mass/molar mass

Molar mass of potassium carbonate = 138.2 g/mol

Number of moles = 65.5 g/138.2g/mol

Number of moles = 0.47 mol
