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
