How many molecules are contained in 6.53 mol of nitrogen gas, n2?

Sagot :

SOLUTION:

There are 6.022 × 10²³ particles in 1 mole of any substance.

[tex]\begin{aligned} \text{number of} \: \text{N}_2 \: \text{molecules} & = \text{6.53 mol} \: \text{N}_2 \times \frac{6.022 \times 10^{23} \: \text{N}_2 \: \text{molecules}}{\text{1 mol} \: \text{N}_2} \\ & = \boxed{3.93 \times 10^{24} \: \text{molecules}} \end{aligned}[/tex]

Hence, there are 3.93 × 10²⁴ molecules in 6.53 mol of nitrogen gas.
