Answer:
153.56g
Explanation:
Number of moles = mass/molar mass
To get the number of moles of the molecule, we divide the number of molecules contained by Avagadro's number, which is 6.02 × 10^23 molecules.
moles = 4.12 × 10^24 ÷ 6.02 × 10^23
number of moles = 0.684 × 10^(24-23)
number of moles = 0.684 × 10^(1)
number of moles = 6.84mol
If the molar mass of the molecule is 22.45 g/mol, the mass of the molecule can be calculated thus:
mass = moles × molar mass (MM)
mass = 6.84 × 22.45
mass = 153.558
mass = 153.56g
