If you are given 243.52 grams of Sb how many miles will you have

kaheart [24]

2 moles

Explanation:

Given parameters:

Mass of Sb = 243.52g

Unknown:

Number of moles = ?

Solution:

The number of moles of any substance can be calculated using the expression below:

Number of moles = $\frac{mass }{molar mass}$

Molar mass of Sb = 121.76g/mol

Now input the parameters:

Number of moles = $\frac{243.52}{121.76 }$ = 2 moles
