Answer:
Mass = 15600 g
Explanation:
Given data:
Number of atoms of oxygen = 5.87 × 10²⁶
Mass of oxygen = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
5.87 × 10²⁶ atom × 1 mole / 6.022 × 10²³ atom
0.975 × 10³ mole
975 mole
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 975 × 16 g/mol
Mass = 15600 g
Dimensional analysis:
5.87 × 10²⁶ atom × 1 mol/6.022 × 10²³ atom × 16 g/ 1 mol = 15600 g
For this, the correct option would be (D)
