If you take molarity (with units mol/L), and multiply it by the molar mass (with units g/mol), you get g/L. Just multiply g/L by 1000 to convert g to mg, and you have ppm (in mg/L of water).

mass percent = (mass of solute / mass of solution) x 100% The molar mass is the sum of the masses of all the atoms in one mole of the compound. The sum of all the mass percentages should add up to 100%.

['A percent v/v solution is calculated by the following formula using the milliliter as the base measure of volume (v):', '% v/v = mL of solute/100 mL of solution.', 'Example:', 'X % = 5.0 mL HCl/100 mL of solution.', 'X/100 = 5.0/100.', '100X = 500.', 'X = 5.0% % v/v.']

Percent Composition - The percent composition of a component in a compound is the percent of the total mass of the compound that is due to that component. To calculate the percent composition of a component in a compound: Find the molar mass of the compound by adding up the masses of each atom.

Divide the molecular weight into the weight of solute in the solution to find the number of moles: 2.7 g ÷ 58 g/mole = 0.047 moles. Divide by the volume of the solution to find molarity: M = (0.047 moles ÷ 0.09 liters) = 0.52 moles/liter.

The equation for molarity is: Molarity = moles of solute/liters of solution. If you know the molarity (concentration) of a solution and the total volume of the solution (make sure it is in liters), you can determine the number of moles of solute. You may then need to convert the moles of solute to grams.

Calculate the percent by mass of each element by dividing the mass of that element in 1 mole of the compound by the molar mass of the compound and multiplying by 100%. Think about your result. ... Percent composition can also be used to determine the mass of a certain element that is contained in any mass of a compound.

How can I calculate molarity when I am given mass in milliliters? Divide the mass by molar mass (mass/molar mass) and convert the milliliters into liters (ml/1000). Now you have moles of solute and liters of solution. Molarity=moles of solute/liters of solution.

For the example, Solution 1 is 0.05 L and Solution 2 is 0.120 L. The final volume = 0.05 L + 0.120L = 0.170 L. Calculate the final molarity of the mixed solution using the equation molarity = moles ÷ liter. For the example, the final molarity is 0.0135 moles ÷ 0.170 liters = 0.079 M.

Considering 37% as the maximum solubility of HCl, you can calculate the molarity using the solution density (1.2 g/mL) and HCl's molar mass (36.46 g/mol). For 1000 mL of solution, you will have 1200g of weight, of which 37% is HCl: 444g.

The weight -- measured in units compatible with the water volume units -- determines the percentage of the solution. Divide it by the volume of water and multiply by 100 to get the percentage. For example, to make 100 milliliters of normal saline solution, which is a 0.9% solution, you need nine grams of salt.

Molarity is defined as the number of moles of a chemical per liter of solution. ... The molecular weight you use must be in units of grams per mole. The result of this calculation will be the number of moles of the compound in the solution. Divide the value of moles you just calculated by the total volume of the solution.

Multiplying the mole fraction by 100 gives the mole percentage, also referred as amount/amount percent (abbreviated as n/n%). For general chemistry, all the mole percents of a mixture add up to 100 mole percent. We can easily convert mole percent back to mole fraction by dividing by 100.

To calculate percent by mass, you need to determine two things: the mass of just the element, and the molar mass of the whole compound. Then, you take the molar mass of just the element and divide it by the molar mass of the whole compound, and multiply by 100%.
