How many mole of calcium (Ca) are in 9.00 x 1016 atoms of Ca?
d1i1m1o1n [39]

Answer:

Number mole of calcium (Ca) = 1.4942 x 10⁻⁷ (Approx.)

Explanation:

Given:

Number of atom in (Ca) = 9 x 10¹⁶

Find:

Number mole of calcium (Ca)

Computation:

Number mole of calcium (Ca) = Number of atom in (Ca) / Avogadro's number

Number mole of calcium (Ca) = (9 x 10¹⁶) / (6.023 x 10²³)

Number mole of calcium (Ca) = 1.4942 x 10⁻⁷ (Approx.)
