This molarity is 3 M.
The molarity of a solution is the amount of substance in a given amount of solute. The units are usually given as moles per liter (or dm3). As such, for each liter you have 0.5 moles of substance (2 divided by 4), so it's a 0.5 molar solution.
This molarity is 3 mol/L.
This is just easy. MOLARITY OF THIS COMPOUND IS 3MOLDM-3.
Molarity = moles of solute/Liters of solution Molarity = 10 moles salt/20 Liters solution = 0.50 M salt solution ----------------------------
0.5M - Apex
2 moles in 0.5 liters will mean 4 moles in 1 liter. So the molarity is 4 molar.
NaF has an atomic mass of 42, therefore if you dissolve 42 grams (1 mole) of it in 2 liters of water you get a molarity of 0.5 moles/Liter.
3 moles in 1 liter = 3 M
Molarity = moles of solute/Liters of solution ( 230 ml = 0.0230 Liters) Molarity = 2.60 moles LiCl/0.230 Liters = 11. 3 M LiCl -----------------
2 moles in 2 liters means 1 mole in 1 liter - so it its molarity is 1.
By it's definition, molarity means how many moles are in a litre. As you already have your moles and it is per litre already, the answer is 2 molar.
The density of liquid water is 1000 grams / liter. Since molarity is given by moles per liter, convert 1000 grams into moles. 1000 grams (1 mole/18.02 grams) = 55.49 moles So, 55.49 moles per liter = 55.49 M. Molarities for solid and gaseous water are different; densities are different, but same steps as I showed for solving.
Molarity = Moles/Unit VolumeSo here Molarity = (0.0255) / (10-2) = 2.55 M
in molarity we dissolved no of moles of solute in 1 dm3 volume of its solution but in molality we dissolved no of moles of solute in 1000 gram or 1 kg of solvent in molarity we don't know the exact amount of solvent quantity but in mplality we know the exact volume of solvent ( water)
Molarity= moles/Liters To change grams to moles you divide by the mole weight which is listed on the periodic table. Mol= grams/mol weight The Mole weight of Magnesium Chloride is 59.8 grams/mol Mol=128g/59.8 Mol=2.14 Now, you put the number of moles and Liters into the equation Molarity=2.14 mol/1L Molarity=2.14 So, the molarity is 2.14 M
The molar mass of PCP (phencyclidine) is 243.387 grams per mole. So 1000 g of PCP is equal to 4.108 moles. If that many moles is in 1000 liters, than the molarity (in moles per liter) is 4.108 ÷ 1000 = 0.0041 M
80g of NaOH dissolved in 250ml. of water find the molarity of this solution ?
Molarity is defined as moles solute/liter of solution6 moles/2 liters solution = 3 molar NOTE: This assumes no volume change and 2L is the final volume of solution.
