If we assume the mass of a large egg is 55 g of which 2.7 g is egg whites and ovomucin makes up 2 %. The molar mass of ovomucin is 254,000 g/mol. How many ovomucin molecules are in a single egg?
Report your answer in scientific notation with 2 decimal place and in the form #.##e##.
The question is not clear to me.
Is that 2.7 g egg white and ovumucin or is that 2.7 g egg white and ovumucin = 2% of the 55 g total?
I believe the latter, my professor isn't always super clear with his questions.
To find the number of ovomucin molecules in a single egg, we need to follow these steps:
1. Calculate the mass of ovomucin in a single egg by multiplying the mass of the egg by its ovomucin percentage:
ovomucin_mass = egg_mass * (ovomucin_percentage / 100)
ovomucin_mass = 55 g * (2 / 100)
ovomucin_mass = 1.1 g
2. Convert the mass of ovomucin from grams to moles using the molar mass of ovomucin:
ovomucin_moles = ovomucin_mass / molar_mass
ovomucin_moles = 1.1 g / 254,000 g/mol
ovomucin_moles ≈ 4.33e-6 mol
3. Calculate the number of molecules using Avogadro's number (6.022e23 molecules/mol):
ovomucin_molecules = ovomucin_moles * Avogadro's number
ovomucin_molecules = 4.33e-6 mol * 6.022e23 molecules/mol
ovomucin_molecules ≈ 2.61e18 molecules
Therefore, there are approximately 2.61e18 ovomucin molecules in a single egg.
