1. Find the Molar Mass of Calcium:
* The molar mass of calcium is approximately 40.08 g/mol. This means that one mole of calcium weighs 40.08 grams.
2. Use the Conversion Factor:
* You have 0.07 moles of calcium. To convert moles to grams, multiply by the molar mass:
0.07 moles Ca * (40.08 g Ca / 1 mole Ca) = 2.8056 grams Ca
Therefore, there are approximately 2.81 grams of calcium in 0.07 moles.
