What is the mass percent of H in ammonium bicarbonate?
The molecular formula of ammonium bicarbonate is NH4HCO3. To find the mass percent of hydrogen (H) in it, we calculate the molar mass of hydrogen in the formula and divide it by the molar mass of the whole compound NH4HCO3, then multiply by 100. The mass percent of hydrogen in ammonium bicarbonate is approximately 5.9%.
What is the mass percent of hydrogen in ammonium phosphate?
The chemical formula for ammonium phosphate is (NH4)3PO4. To calculate the mass percent of hydrogen, you first need to calculate the molar mass of the entire compound and then determine the contribution of hydrogen to the total mass. The molar mass of (NH4)3PO4 is 149.09 g/mol, and the total mass of hydrogen in the compound is 3*(1.01 g/mol) = 3.03 g. Therefore, the mass percent of hydrogen in ammonium phosphate is (3.03 g / 149.09 g) * 100% = 2.03%.
What is the formula mass of h20?
The formula mass of H2O (water) is calculated by adding the atomic masses of the elements present in the compound. The atomic masses of hydrogen (H) and oxygen (O) are approximately 1 and 16, respectively. Therefore, the formula mass of H2O is 1 (atomic mass of H) * 2 (number of hydrogen atoms) + 16 (atomic mass of O) = 18.
What is the percent composition of the compound formed when 2.70 g of aluminum combine with oxygen to form 5.10 g of aluminum oxide?
The molar mass of aluminum oxide is 101.96 g/mol. To find the percent composition, divide the mass of each element by the molar mass of the compound and multiply by 100. The percent composition is 52.72% aluminum and 47.28% oxygen.
What is the mass percent of chlorine in CCl3F?
The molar mass of CCl3F is 137.37 g/mol. The mass of chlorine in one molecule of CCl3F is 106.38 g/mol. To calculate the mass percent of chlorine in CCl3F, divide the mass of chlorine by the molar mass of CCl3F and multiply by 100. This gives a mass percent of 77.48%.
