How many moles of tin are there in 50 g of tin (II) oxide

Moles of tin = 0.37 mol

Explanation:

Given data:

Mass of tin oxide = 50 g

Moles of tin = ?

Solution:

Number of moles of SnO:

Number of moles = mass/molar mass

Number of moles = 50 g/ 134.71 g/mol

Number of moles = 0.37 mol

We can see there is only one mole of Sn is present in one mole of tin oxide.

Thus in 0.37 mol  of tin oxide,

0.37 mol × 1 = 0.37 mol of tin
