How do you calculate molar mass and molecular mass?
Find the atomic mass for each element using the mass shown in the Periodic Table or Atomic Weight Table. Multiply the subscript (number of atoms) times that element's atomic mass and add the masses of all the elements in the molecule to obtain the molecular mass.
How do I calculate molarity?
As mass / volume = molarity * molar mass , then mass / (volume * molar mass) = molarity . Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M . You can also use this molarity calculator to find the mass concentration or molar mass.

What is the molarity of a solution containing 2.5 g NaCl of solute in a 0.5 liter solution?
A 2.5 M solution is 2.5 moles per liter (Molarity is just the number of moles per liter). Therefore, 0.5 L would contain 1.25 mol.
How do you calculate mass per litre?
Concentration (g/L)=mass of solute (g)volume of total solution (L)=15 g5 liters=3 g/L Concentration (g/L) = mass of solute (g) volume of total solution (L) = 15 g 5 liters = 3 g/L The concentration of the NaOH solution is 3 g/L.
How do you convert mass to concentration?
As mass / volume = molarity * molar mass , then mass / (volume * molar mass) = molarity . Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M . You can also use this molarity calculator to find the mass concentration or molar mass.
How do you calculate molarity from mass?
As mass / volume = molarity * molar mass , then mass / (volume * molar mass) = molarity . Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M .
How do you find liters from molarity?
Compute the volume of a solution in liters, given the number of moles and molarity, by dividing the number of moles by the molarity in units of moles per liter. For example, a solution containing 6.0 moles and a having a molarity of 3.0 moles per liter has a volume of 2.0 moles per liter.
What is the molecular formula of Na2SO4?
Na2SO4Sodium sulfate / Formula
How do you calculate equivalents?
Equivalent units describe how much work has been done on a certain number of physical items. To simply calculate equivalent units, you can multiply the number of physical items by the percentage of the work done on them. For two items that are 50% done, you would have one equivalent unit (2 x 50% = 1).
What mass of sucrose C₁₂h₂₂o₁₁ is needed to make 500.0 mL of a 0.200 M solution molar mass of C 12.01 g H 1.01 g/o 16.00 g?
So we need approx. 35⋅g sucrose.
What mass of c12h22011 sucrose is needed to prepare 255 mL of a 0.570 M solution of sucrose in water?

How do you calculate mass from volume?
Volume equals mass divided by density; and. Mass equals density times volume.
What mass of NaCl do you need to use to make the solution?
If a different molarity is required, then multiply that number times the molar mass of NaCl. For example, if you wanted a 0.5 M solution, you would use 0.5 x 58.44 g/mol of NaCl in 1 L of solution or 29.22 g of NaCl.
How do you calculate moles per Litre?
1 liter of water weighs 1000 g, and, as molarity is the number of moles per liter; finding the molarity of water is the same as finding the number of moles of water in 1000 g. We therefore divide the weight by the molar mass to get moles, 1000 / 18.02 = 55.5 M.
