Question

How many moles are there in 3.80x10^22 molecules of CCI4?

Answer 1

Answer:

0.0646 mole.

Explanation:

The following data were obtained from the question:

Number of molecules = 3.89×10²² molecules

Number of mole =?

The number of mole present in 3.89×10²² molecules of CCl₄ can be obtained as follow:

From Avogadro's hypothesis:

6.02×10²³ molecules = 1 mole

Therefore,

3.89×10²² molecules = 3.89×10²² molecules × 1 mole / 6.02×10²³ molecules

3.89×10²² molecules = 0.0646 mole

Thus, 0.0646 mole is present in 3.89×10²² molecules of CCl₄.
