You have too many problems in one post.
Your symbolism is baffling.
2. To find the total mass of the mixture, you need to add the mass of chloroform and eucalyptol. The mass of chloroform is given as 0.300 kilograms, which is equal to 300 grams. The mass of eucalyptol is given as 21.0 grams. Add these two values to get the total mass of the mixture.
3. The concentration of a solution is typically expressed in terms of moles per liter (mol/L) or molarity. To find the molarity, you need to determine the number of moles of solute (sodium chlorine) and the volume of the solution (in liters). The mass of the solute is given as 1.170 grams. Convert this mass to moles using the molar mass of sodium chlorine. Divide the mass of the solute in moles by the volume of the solution in liters to calculate the molarity.
4. The % by volume of a solution is calculated by dividing the volume of the solute by the total volume of the solution and multiplying by 100. In this case, you are given the number of moles of alcohol (30.0 moles) and water (7.0 moles). The volume can be obtained by converting moles to liters using the molar volume of the substance. Calculate the total volume of alcohol and water, then divide the volume of alcohol by the total volume and multiply by 100 to get the % by volume.
5. To calculate the mole fraction of the solute in a solution, you need to determine the number of moles of ethanol (the solute) and the total number of moles in the solution. The 40% by mass ethanol solution means that 40 grams of ethanol are present in every 100 grams of the solution. Convert the mass of ethanol to moles using the molar mass of ethanol. Divide the moles of ethanol by the total moles in the solution (which you can calculate by converting the mass of water to moles using the molar mass of water) to get the mole fraction of the solute.
6. The molarity of a solution is calculated by dividing the number of moles of solute by the volume of the solution in liters. In this case, you are given the number of moles of sodium OH (600.00 moles) and the mass of sodium OH (15.0 grams). Convert the mass of sodium OH to moles using the molar mass of sodium OH. Then divide the number of moles by the volume of the solution in liters to get the molarity.
7. To calculate the molarity of a solution given its mass percentage, you need to convert the mass percentage to moles. In this case, the mass percentage of calcium chlorine2 is given as 45.0%. This means that for every 100 grams of the solution, there are 45.0 grams of calcium chlorine2. Convert this mass to moles using the molar mass of calcium chlorine2. Then divide the moles of calcium chlorine2 by the volume of the solution in liters to get the molarity.
