Question

If you have 6.00 x 10^24 molecules of oxygen how many moles of oxygen would you have?

Answer 1

Answer:

9.96 moles of oxygen

Explanation:

Given data:

Number of molecule of oxygen = 6.00×10²⁴ molecules

Number of moles of oxygen = ?

Solution:

1 mole contain 6.022 ×10²³ molecules

6.00×10²⁴ molecules × 1 moles of oxygen  / 6.022 ×10²³ molecules

0.996×10¹ moles of oxygen

9.96 moles of oxygen

The number 6.022 × 10²³ is called 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.
