12.04moles
Explanation:
Given parameters:
Number of molecules = 7.25 x 10²⁴molecules
unknown:
Number of moles = ?
Solution:
The moles of a substance is the amount of substance that contains avogadro's number of particles:
1 mole of a substance = 6.02 x 10²³
x moles of the compound will contain: ![\frac{7.25 x 10[tex]^{24}](https://tex.z-dn.net/?f=%5Cfrac%7B7.25%20x%2010%5Btex%5D%5E%7B24%7D)
}{6.02 x 10
}[/tex] = 12.04moles
This gives 12.04moles

We assume that this gas is ideal. Therefore, we can use the ideal gas equation which is expressed as:
PV=nRT
We manipulate this equation to give us an expression which will correspond to density. We do as follows:
PV= nRT
P/RT = n/V where n = m/MM
P(MM) /RT = m/V = density
Density = 1.00 (17.03) / 0.08206 (435)
Density = 0.48 g / L
