2.50x10^2 is 250cm^3. 7.5gx4 is 30g per litre. The molecular weight of NH4Br is 97.942g/mol. 30/97.942 is 0.3063 molar.
The molarity is 0,41 mol/L.
The solubility of NH4Br in water at 60°C is 122 g/100g H2O. To produce a saturated solution, the mass of NH4Br that must be dissolved in 200g of water can be calculated using this ratio. Therefore, the total mass of NH4Br needed would be (122/100) x 200 = 244 grams.
Molarity = Grams/(Molecular Weight X Volume)
Molarity = Grams/(Molecular Weight X Volume)
If 1,1 is grams the molarity is 0,317.
grams divided by the molecular weight to get to moles moles divided by volume to get molarity
The molarity is 0,125 M.
Depending on the volume of water ! For 1 L, the molarity is approx. 0,1.
The molarity of the solution is 0.5 M.
Magnesium sulfide react with water.This is not solubilty and molarity cannot be applied.
To calculate the molarity of the solution, first convert the mass of HCl to moles using its molar mass. Then, divide the number of moles by the volume of the solution in liters (500 cm3 = 0.5 L) to get the molarity.
Increasing the amount of the solute in the solution the molarity and the density of this solution increases.
