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.)
Protons, neutrons, and electrons are the fundamental subatomic particles.
Answer:
Explanation:
The reason for that is because atoms make elements needed for survival(oxygen, hydrogen, nitrogen, carbon, etc.).
