Question

How many moles are there in 2.00 x 1019 molecules of CCl4?

Answer 1

TOPIC :- MOLE CONCEPT

CONCEPT :- In 1 mole of a molecule , there are total 6.022 × 10^23 molecules.

Hence, no. of moles = $\frac{no. \: of \: molecules}{6.022 \times {10}^{23} }$

Steps :-

Given, no. of molecules = 2 × 10^19.

Hence, number of molecules as per formula = $\frac{2 \times {10}^{19} }{6.022 \times {10}^{23} } = 0.33 \times {10}^{ - 4} moles$

Answer 2

Answer:

0.33×10-4 molecules
