What will be the molarity of a solution if 5 g NaOH is dissolved in 500 of water?
Complete answer: That means 0.128 moles of NaOH is dissolved in 500mL of water, now to calculate Molarity we must change the si unit of volume from mL to liter.
What will be the molarity of solution if 4g of NaOH dissolve in 200ml?
So, the molarity of the solution will be 1M .
What is the molarity of a solution containing 5 moles of solute in 250 milliliters of solution?
The molarity of the solution is 5.1 mol/L .
What is the molarity of NaOH in solution prepared?
To calculate the number of moles one must know the molecular mass of the substance. The molecular weight of sodium hydroxide is $40g/mol$. The molarity of sodium hydroxide in the solution prepared by dissolving its \[4g\] in water to make a solution of \[250mL\] is $0.4M$.
What is the molarity of 4g of NaOH?
Calculate the molarity of the solution. Molarity of solution (M)=Moles of NaOHVolume of solution in litres=0.1 mol0.5L=0.2mol L-1=0.2M.
What is the molarity of a solution containing 5 moles of solute in 250 mL of solution?
How many moles of NaOH are needed to dissolve BrO3⊝?
[SOLVED] 4gm of NaOH is dissolved in 250 ml of a solution. calculate its molarity. . Then, the resulting solution requires 45 mL of As 3+ solution to reduce BrO 3⊝
How do you calculate molarity in chemistry?
Quick Review of Calculating Molarity. To calculate molarity: Find the number of moles of solute dissolved in solution, Find the volume of solution in liters, and. Divide moles solute by liters solution.
How do you find the molarity of KMnO4 solution?
Calculate the molarity of a solution prepared by dissolving 23.7 grams of KMnO 4 into enough water to make 750 mL of solution. This example has neither the moles nor liters needed to find molarity, so you must find the number of moles of the solute first.
What is the relationship between molarity and concentration?
molarity = concentration / molar mass. The concentration denotes the mass concentration of the solution, expressed in units of density (usually g/l or g/ml). Molar mass is the mass of 1 mole of the solute. It is expressed in grams per mole. It is a constant property of each substance – for example, the molar mass of water is approximately equal
