To find the percent composition of potassium chlorate (KClO3), you first need to calculate the molar mass of the compound. The molar mass is approximately 122.55 g/mol for potassium (K), 35.45 g/mol for chlorine (Cl), and 48.00 g/mol for three oxygen atoms (O). This gives a total molar mass of about 122.55 + 35.45 + 48.00 = 206.00 g/mol. The percent composition of each element is then calculated by dividing the mass of each element by the total molar mass and multiplying by 100: K (59.50%), Cl (17.20%), and O (23.30%).

What is the percent composition for 29.0 g of Argon combine completely with 4.30 g of Sulfur?
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%.
What is the percent of a composition of a compound containing 8.6g of Be and 52.4g of I?
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%.
