Answer:
11.6 mL is the volume for 5.33 × 10²² molecules of hexane
Explanation:
We analyse data:
5.33 × 10²² molecules of hexane
0.6548 g/mL
86.17 g/mol
First of all, we determine the moles of hexane that contain 5.33 × 10²² molecules
6.02×10²³ molecules are contained in 1 mol
5.33 × 10²² molecules must be contained in (5.33 × 10²² . 1) / NA = 0.088 moles
Now we convert the moles to mass → 0.088 mol . 86.17 g/m = 7.63 g
Finally we apply density to determine the volume
Density = mass / volume → Volume = Mass / Density
Volume = 7.63 g / 0.6548 g/mL = 11.6 mL
