Answer:
36 grams of Calcium
Step-by-step explanation:
In order to calculate the gram of calcium, divide the total number of Calcium atoms by Avogadro's number:
(2.17 x 10^25)/(6.02 x 10^23) =
2.17/6.02 * 10^25/10^23 =
2.17/6.02 * 10^25/10^23 =
0.36 * 10^(25-23) =
0.36 * 10^2 =
0.36 * 100 = 36 grams of Calcium
