Answer: 568g/mol
Explanation:
It should be noted that there are 40 atoms of carbon in lycopene.
Since mass of 1 carbon = 12g/mol
Mass of 40 carbon atoms = 40 × 12g/mol = 480g/mol
Let the molar mass of lycopene be represented by x.
Therefore the molar mass of carbon = x × mass percent of carbon in lycopene
x × 84.49% = 480g/mol
x × 0.8449 = 480g/mol
x = 480/0.8449
x = 568g/mol
The molar mass of lycopene is 568g/mol

The molality of a solution containing 3. 0 moles of NaCl and 100. 0 moles of water is 30 mol/kg.
The number of moles of solute in a solution equal to 1 kg or 1000 g of solvent is referred to as its molality. Mole per kilogram of solvent is the SI unit for molality.
Given:
3.0 moles of NaCl in 100 moles of water.
To find:
The molality of the solution
The moles of solute (NaCl) = 3.0 moles
The mass of solvent (water) = 100 moles (0.1 kg/mol)
Molality of a solution = Number of Moles of solute/ Mass of solvent(kg)
= 3.0 moles/0.1 kg/mol
= 30 mol/kg
