1.80 mol of calcium refers to a quantity of calcium atoms or ions, where 1 mole is defined as approximately (6.022 \times 10^{23}) entities (Avogadro's number). Therefore, 1.80 mol of calcium contains about (1.08 \times 10^{24}) calcium atoms. Calcium, with the chemical symbol Ca, is a metallic element that plays a vital role in biological systems and is commonly found in compounds like calcium carbonate and calcium phosphate.

When 10.0 mol of calcium metal is reacted with 3.4 mol of oxygen gas how much calcium oxide is produced?
To determine how much calcium oxide is produced, we first need to consider the balanced chemical reaction: 2 Ca + O₂ → 2 CaO. From the reaction, 2 moles of calcium react with 1 mole of oxygen to produce 2 moles of calcium oxide. Given 10.0 mol of calcium and 3.4 mol of oxygen, calcium is in excess since it requires only 1.7 mol of oxygen (10.0 mol Ca / 2 = 5 mol CaO produced). Therefore, 3.4 mol of oxygen can fully react with 6.8 mol of calcium, yielding 6.8 mol of calcium oxide produced.
What is the heat of fusion for calcium?
The heat of fusion for calcium is 8.54 kJ/mol.
What is the mass percent of calcium in calcium bromide?
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 of 1.80 mol of calcium?
To find the mass of 1.80 moles of calcium, you can use the molar mass of calcium, which is approximately 40.08 g/mol. By multiplying the number of moles by the molar mass, you calculate the mass: 1.80 mol × 40.08 g/mol = 72.144 g. Therefore, the mass of 1.80 moles of calcium is about 72.14 grams.
