The molar mass of calcium bromide (CaBr2) is 199.89 g/mol. Calcium has a molar mass of 40.08 g/mol. The mass percent of calcium in calcium bromide is calculated as (40.08 g/mol / 199.89 g/mol) x 100%, which is approximately 20.04%.
What is the mass in grams of 0.330mol of calcium?
The mass is 0.330 mol Ca (40.08 g/mol) = 13.2 g Ca
How do you calculate mass fractions of calcium and fluorine in fluorite?
To calculate the mass fractions of calcium and fluorine in fluorite (CaF₂), first determine the molar masses of calcium (Ca, approximately 40.08 g/mol) and fluorine (F, approximately 19.00 g/mol). The formula for fluorite shows that one mole of calcium combines with two moles of fluorine, giving a total molar mass of CaF₂ as 40.08 g/mol + 2 × 19.00 g/mol = 78.08 g/mol. The mass fraction of calcium is calculated by dividing the molar mass of calcium by the total molar mass (40.08 g/mol / 78.08 g/mol), and the mass fraction of fluorine is calculated by dividing the total mass of fluorine (2 × 19.00 g/mol) by the total molar mass (38.00 g/mol / 78.08 g/mol).
How do you find the molar mass of calcium chloride?
To find the molar mass of calcium chloride (CaCl₂), first identify the atomic masses of its constituent elements: calcium (Ca) has an atomic mass of approximately 40.08 g/mol, and chlorine (Cl) has an atomic mass of about 35.45 g/mol. Since there are two chlorine atoms in calcium chloride, calculate the molar mass as follows: 40.08 g/mol (Ca) + 2 × 35.45 g/mol (Cl) = 111.98 g/mol. Therefore, the molar mass of calcium chloride is approximately 111.0 g/mol.
What is the molecular mass of calcium bicarbonate?
The molecular mass of calcium bicarbonate (Ca(HCO₃)₂) can be calculated by adding the atomic masses of its constituent elements. Calcium (Ca) has an atomic mass of approximately 40.08 g/mol, hydrogen (H) about 1.01 g/mol, carbon (C) about 12.01 g/mol, and oxygen (O) about 16.00 g/mol. Therefore, the molecular mass of calcium bicarbonate is approximately 162.11 g/mol.
What is the mass in grams of 0.330 mol of calcium?
To find the mass in grams of 0.330 mol of calcium, you need to multiply the number of moles by the molar mass of calcium. The molar mass of calcium is approximately 40.08 grams/mol. So, 0.330 mol * 40.08 g/mol = 13.23 grams of calcium.
