To find the percent composition, first calculate the total mass by adding the masses of Argon and Sulfur. Then, determine the percent composition of each element by dividing the mass of that element by the total mass and multiplying by 100. In this case, the percent composition of Argon is about 87.1%, and the percent composition of Sulfur is about 12.9%.
To find the percent composition of each element in the compound, you first calculate the molar mass of Be (9.01 g/mol) and I (126.90 g/mol). Then, calculate the percent composition of each element by dividing the mass of the element by the total molar mass of the compound and multiplying by 100. The percent composition of Be is 5.14% and the percent composition of I is 94.86%.
