What is the molarity of Na 2 CO 3 solution?

The molar mass of Na2CO3 is 106 g/mole.

What is the molarity of 5 Na2CO3?

The molecular weight of Na2CO3 is 106 g/mol. Calculate the number of moles is represented by 5 g. This is EQUAL TO 5 g/106 g/mol or 0.0472 mol. MOLARITY= 0.0472 mol/0.2 L = 0.236 mol/L or 0.236 M.

How do you find the molarity of a dissolved solution?

The molarity (M) of a solution is the number of moles of solute dissolved in one liter of solution. To calculate the molarity of a solution, you divide the moles of solute by the volume of the solution expressed in liters.

How many moles of solute in Co(NO3)2?

we know that molar mass of Co (NO 3) 2.6H 2 O = 291 g / mol Molarity = Number of moles / Volume of solution Hence, the number of moles of solute = given weight/molar mass = 30/291= 0.103 mol Molarity = 0.103/ 4.3 = 0.023M

What is the molarity of a solution?

Answer: Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution. Explanation: To get the molarity, you divide the moles of solute by the litres of solution.

How do you calculate liters of solution from 1 mol of NaOH?

Solution: 1 mol of NaOH has a mass of 40.00 g, so. #”Moles of NaOH” = 15.0 cancel(“g NaOH”) × “1 mol NaOH”/(40.00 cancel(“g NaOH”)) = “0.375 mol NaOH”#. #”Litres of solution” = 225 cancel(“mL soln”) × “1 L soln”/(1000 cancel(“mL soln”)) = “0.225 L soln”#.
