Introduction

In chemistry, determining the composition of a mixture is a crucial task that helps us understand the properties and behavior of the mixture. In this article, we will discuss how a student can determine the mass percent of Cl in a mixture of $$MgCl_2(s)$$ and $$NaNO_3(s)$$.

The Mixture and Its Composition

The mixture in question contains 9.8 g of $$MgCl_2(s)$$ and $$NaNO_3(s)$$. The student has measured that the mixture contains 0.050 mol of $$MgCl_2(s)$$. To determine the mass percent of Cl in the mixture, we need to first calculate the mass of Cl in the $$MgCl_2(s)$$.

Calculating the Mass of Cl in $$MgCl_2(s)$$

The molar mass of $$MgCl_2(s)$$ is 58.33 g/mol. Since the mixture contains 0.050 mol of $$MgCl_2(s)$$, the mass of $$MgCl_2(s)$$ in the mixture is:

0.050 mol x 58.33 g/mol = 2.9175 g

The molar mass of Cl is 35.45 g/mol. Since there are two Cl atoms in each molecule of $$MgCl_2(s)$$, the mass of Cl in the $$MgCl_2(s)$$ is:

2 x 35.45 g/mol = 70.9 g/mol

The mass of Cl in the $$MgCl_2(s)$$ is:

2.9175 g x (70.9 g/mol / 58.33 g/mol) = 3.55 g

Calculating the Mass Percent of Cl in the Mixture

To calculate the mass percent of Cl in the mixture, we need to divide the mass of Cl in the mixture by the total mass of the mixture and multiply by 100.

Mass of Cl in the mixture = 3.55 g Total mass of the mixture = 9.8 g

Mass percent of Cl in the mixture = (3.55 g / 9.8 g) x 100 = 36.22%

Conclusion

In this article, we have discussed how a student can determine the mass percent of Cl in a mixture of $$MgCl_2(s)$$ and $$NaNO_3(s)$$. By calculating the mass of Cl in the $$MgCl_2(s)$$ and dividing it by the total mass of the mixture, we can determine the mass percent of Cl in the mixture.
