How many moles are in 16.5g of calcium?

Answer 1

Calcium, Ca has Atomic Mass of 40.1
Amount of Ca = 16.5/40.1 = 0.411mol
There are 0.411 moles of calcium in a 16.5 gram sample.

Answer 2

To find the number of moles in 16.5g of calcium, first determine the molar mass of calcium (Ca), which is approximately 40.08g/mol. Then, divide the given mass by the molar mass to get the number of moles. In this case, 16.5g ÷ 40.08g/mol ≈ 0.411 moles of calcium.
