We would then use the molar mass of barium hydroxide to find the moles of this compound that we have. If you do this correctly, you should get 0.07. This is only our empirical formula, so we need to find the molecular formula by dividing 0.56 H2O / 0.07 Ba(OH)2 = 8 Therefore, we...
- The freezing point of pure water is 0°C. The solution freezes at -0.2°C. - Therefore, ΔTf = 0 - (-0.2) = 0.2°C. 2. Use the freezing point depression formula: ΔTf=Kf⋅m Where: - ΔTf = 0.2°C - Kf = 1.86 kg/mol 3. Rearranging the formula to find molality (m)...
Step 3: Calculate the number of moles of ethyl alcoholTo find the number of moles, we use the formula:Number of moles=massmolar massSubstituting the values:Number of moles=50.0 g46.0 g/mol≈1.08696 moles Step 4: Calculate the molarity of the solutionMolarity (M) is defined as the number...
The answer is that moles give us a consistent method to convert between atoms or molecules and grams. It's simply a convenient unit to use when performing calculations. You may not find it too convenient when you're first learning how to use it, but once you become familiar with it, a...
The molar ratio compares the number of moles in a balanced equation. This is the comparison between the coefficients in front of the chemical formulas. If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species. ...
