To calculate the number of molecules in 45 grams of water (H₂O), first determine the molar mass of water, which is approximately 18 g/mol. Then, divide the mass of water by its molar mass: 45 g ÷ 18 g/mol = 2.5 moles of water. Finally, use Avogadro's number (approximately (6.022 \times 10^{23}) molecules/mol) to find the number of molecules: 2.5 moles × (6.022 \times 10^{23}) molecules/mol ≈ (1.51 \times 10^{24}) molecules.

What is the molecular mass of 8.02 grams of solute in 861 grams of water lower the freezing point to -0.430 degrees C?
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.

What is the mass percent of calcium chloride if 45g of cacl2 is dissolved in 320 g of water?
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%.
