The molecular mass of water vapour is 18.01528
You divide the 6.073 by 6.022x1023 (avagadros number) to get the moles, then multiply by molecular mass (18) to get mass in grams
To calculate the molecular mass of the solute, we need to use the formula for freezing point depression: ΔTf = Kf * m. Given that the ΔTf is -0.430°C, the molal concentration (m) of the solute can be found by dividing the grams of solute by the grams of water. Substituting these values into the formula allows us to solve for Kf, which can eventually be used to determine the molecular mass of the solute.

1 ounce = 28.3527g So, 45g divided by 28.3527 = 1.587 ounces.
45 grams of water is 3 tbsp.
Mass percent of calcium chloride can be calculated by dividing the mass of calcium chloride by the total mass of the solution (calcium chloride + water) and then multiplying by 100. In this case, the mass percent would be (45g / (45g + 320g)) * 100 ≈ 12.35%.
The volume of 45g of face cream can vary depending on its density. However, a rough estimation would be approximately 45mL, as 1g of most creams is roughly equivalent to 1mL in volume. It is best to check the packaging for specific information on the product.

The molecular abbreviation for water is H2O.
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.
To calculate the molecular mass of a compound, you add up the atomic masses of all the atoms in the compound. This can be found on the periodic table.
