Answer :
Final answer:
There are approximately 0.125 moles of calcium in 5.00 grams of calcium, calculated using the molar mass of calcium (40.08 g/mol).
Explanation:
To calculate the number of moles of calcium in 5.00 g of calcium, we need to use the molar mass of calcium. The molar mass of calcium (Ca) is roughly 40.08 g/mol. We can use the following formula to convert grams to moles: Number of moles = Mass (g) ÷ Molar mass (g/mol).
Let's perform the calculation:
Number of moles = 5.00 g ÷ 40.08 g/mol = 0.125 moles of calcium (to two decimal places).
So, there are approximately 0.125 moles of calcium in 5.00 g of calcium.
Answer:
Number of moles = 0.125 mol
Explanation:
Given data:
Mass of calcium = 5.00 g
Number of moles = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of calcium = 40 g/mol
By putting values,
Number of moles = 5.00 g/ 40 g/mol
Number of moles = 0.125 mol
