The Percent Composition of Mg and Br in a Mixture

Combining Mg and Br

When 15.6 g of Mg is combined with 13.9 g of Br, we can calculate the percent composition of each element in the mixture.

Calculating Percent Composition

To calculate the percent composition of Mg in the mixture, we first need to find the total mass of the mixture. Adding the masses of Mg and Br together gives us:

Total mass: 15.6 g (Mg) + 13.9 g (Br) = 29.5 g

Next, we determine the percent composition of each element:

Mg Percent Composition

Mg: (15.6 g / 29.5 g) x 100% = 52.9%

Br Percent Composition

Br: (13.9 g / 29.5 g) x 100% = 47.1%

This means that in the mixture of 15.6 g Mg and 13.9 g Br, Mg makes up 52.9% of the total mass while Br makes up 47.1%.

What is the percent composition of Mg and Br in the mixture when 15.6 g of Mg is combined with 13.9 g of Br?

Answer:

Mg: 52.9%

Br: 47.1%

Explanation:

The percent composition of Mg and Br in the mixture is 52.9% and 47.1% respectively.
