we are asked to find the volume of hexane. Density is mass per given volume.
1 mol of any substance is made of 6.022 x 10²³ units, these units could be atoms making up an element or molecules making up a compound.
the number of molecules in hexane has been given therefore we can find the number of moles of hexane
6.022 x 10²³ molecules make up - 1 mol
therefore 5.33 x 10²² molecules make - 1 / (6.022 x 10²³) x 5.33 x 10²²
= 0.0885 mol
since we know the molar mass and number of moles, mass of hexane can be calculated
mass of hexane = 86.17 g/mol x 0.0885 mol = 7.63 g
density has been given, therefore we can find the volume
volume = mass / density
volume = 7.63 g / 0.6548 g/ml = 11.7 ml
volume of hexane is 11.7 ml
Hexane is an organic compound, which has six carbon atoms in a straight line. The volume of hexane that contains 5.33 × 1022 molecules of hexane is 11.7 ml.
Hexane is a solvent that is widely used in industries to extract edible oils from vegetables.
Its formula is [tex]\bold{C_6H_1_4 }[/tex]
Given,
The density of hexane is 0.6548 g/ml
Molar mass is 86.17 g/mol.
1 mol = 6.022 x 10²³ molecules
Therefore, 5.33 x 10²² molecules make
[tex]\bold{\dfrac{1}{(6.022 \times 10^2^3)} \times 5.33 \times 10^2^2 = 0.0885 mol}[/tex]
Since we know the molar mass and number of moles of the compound, the mass of hexane will be
[tex]\bold{Mass\; of\; hexane = 86.17 g/mol \times 0.0885 mol = 7.63 g}[/tex]
Now, calculating the volume by the density
[tex]\bold{Volume = \dfrac{mass}{density}} \\\\\bold{Volume = \dfrac{7.63 g}{0.6548 g/ml }=11.7\;ml}[/tex]
Thus, the volume of hexane is 11.7 ml.
