45g = 0.045kg
2.35 grams water (1 mole H2O/18.016 grams) = 0.130 moles water ===============
Calculate the molecular mass of the nonionic solutes. 8.02 grams of solute in 861 grams of water lower the freezing point to -0.430 ±C.

We need to know the density of the lotion to calculate the volume. V=M/d
1 ounce = 28.3527g So, 45g divided by 28.3527 = 1.587 ounces.
45 grams of water is 3 tbsp.

the given molecular weight is divided by volume
To calculate the relative molecular mass (Mr) of a molecule, add up the atomic masses of all the atoms in the molecule as shown in its molecular formula. For example, the Mr of H2O (water) is calculated by adding the atomic masses of 2 hydrogen atoms and 1 oxygen atom.
