Divide 175 by 750 and multiply by 1000 to get g/l. This gives you 233.3333g/litre. The molecular weight for KNO3 is 101.1g/mol. 233.333/101.1 is 2.31 molar.

How much 80 g of glucose C6H12O6 is added to enough water to make 750ml of sugar solution What is the molarity?
Moles of glucose = 80g/180g/mol = 0.444 moleMolarity = 0.444/0.75L = 0.5926 M
What is the molarity of 2.5 mol KCI in 1.0 L of solution?
You want to get the concentration that would be in a litre. for every 750ml, there is 1 mol. so 1/750, x1000 will give you 1.333 molar. i.e. 1.333 moles in every litre.
How on earth do you find the molarity of a 750 ml solution containing 346g of potassium nitrate?
Well potassium nitrate has a molecular weight of 101. If there are 346g in 750ml there will be 346 x 1000/750 = 461.334 g in 1 liter. The solution is thus 461.334/101 = 4.57 molar (2 decimal places).
What is the weight of 750ml?
That depends on whether it s 750ml of lead, 750ml of foam, or something in between.
What is molarity poh and pH of 4.50G of NaOH if diluted in up to 750 ml of H2O?
MW NaOH is 23+16+1 = 40. 4.5g in 750ml is 6.0g in 1L. Molarity is 6/40 = 0.15 OH- concentration is 0.15, pOH is -log100.15 = 0.82 H+ concentration is 10-14/0.15 = 6.67x10-13 pH is -log10 6.67x10-13 = 12.18
A solution contains 85.0 g of NaNO3 and has a volume os 750 mL find the molarity of the solution?
Molarity is mols of solute over liters of solution. 85.0g NaNO3 (1mol/85g ) = 1mol 750ml = 0.75 Liters so, 1/0.75 = 1.3 Molar
What is the molarity of a 750.0 milliliter solution containing 2.5 moles of solute?
You have 2.5 moles in 750ml. However molar means per 1000ml. Therefore 2.5/750*1000 gives you your answer. The answer is 3.333 molar.

750 ml of 20M HCl is mixed with 250 ml of 60M HCl What is the new molarity?
Molarity of a solution is the number of moles of the solute divided by the volume of the solution (in liters). If 750 ml of 20M HCl is mixed with 250 ml of 60M HCl, we first find the total number of moles of HCl in our new solution. Using that same formula, M=moles/V, we cansee that moles=MV. In the first solution we have (20M)(0.750L) = 15 moles. In the second, (60M)(0.250L) = 15 moles, so we have a total of 30 moles in our new solution, which also has a volume of 750mL + 250mL = 1L. The molarity of the new solution is 30 moles/1L = 30M
