Answer:

75.924 g

Explanation:

To answer this question we first need to calculate the molar mass of Ga₂(SO₃)₃:

Molar Mass of Ga₂(SO₃)₃ = (Molar Mass of Ga)*2 + (Molar Mass of SO₃)*3

  • Molar Mass of SO₃ = Molar Mass of S + (Molar Mass of O)*3 = 80.06 g/mol

Molar Mass of Ga₂(SO₃)₃ = (69.72 g/mol)*2 + (80.06 g/mol) * 3

  • Molar Mass of Ga₂(SO₃)₃ =  379.62 g/mol

Then we convert 0.20 moles to grams, using the molar mass of Ga₂(SO₃)₃:

  • 0.20 mol Ga₂(SO₃)₃ * 379.62 g/mol = 75.924 g

Mass of 0.20 moles of Ga₂(SO₃)₃ is 75.924 g

Number of moles:

It is defined as the ratio of given mass over molar mass.

Given:

Number of moles= 0.20 moles

To find:

Mass=?

We need to calculate molar mass of Ga₂(SO₃)₃ first:

Molar Mass of Ga₂(SO₃)₃ = (Molar Mass of Ga)*2 + (Molar Mass of SO₃)*3

Molar Mass of SO₃ = Molar Mass of S + (Molar Mass of O)*3 = 80.06 g/mol

Molar Mass of Ga_2(SO_3)_3 = (69.72 g/mol)*2 + (80.06 g/mol) * 3

Molar Mass of Ga₂(SO₃)₃ =  379.62 g/mol

Then we convert 0.20 moles to grams, using the molar mass of Ga₂(SO₃)₃:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}} \\\\\text{Given mass}=\text{Number of moles}*\text{Molar mass}\\\\\text{Given mass}=0.20 moles*379.62 g/mol\\\\\text{Given mass}=75.92 grams\\[/tex]

Thus, the mass of 0.20 moles of Ga₂(SO₃)₃ is 75.92 grams.
