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).
How much 80 g of glucose C6H12O6 is added to enough water to make 750ml of sugar solution What is the molarity?
To find the molarity of the sugar solution, we first need to convert the mass of glucose to moles. The molar mass of glucose (C6H12O6) is 180 g/mol. So, 80 g of glucose is equal to 80/180 = 0.444 moles. Next, calculate the molarity by dividing moles of glucose by liters of solution (0.75 L), Molarity = 0.444 moles / 0.75 L = 0.592 M.
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
What is the weight of 750ml?
That depends on whether it s 750ml of lead, 750ml of foam, or something in between.
What is the mass of the solute in 750mL of 0.188M lithium sulfide?
To find the mass of the solute (lithium sulfide) in 750mL of 0.188M solution, you need to multiply the volume of the solution (750mL) by the molarity (0.188 mol/L) and the molar mass of lithium sulfide (Li2S). First, calculate the number of moles in 750mL of 0.188M solution, then convert moles to grams using the molar mass of Li2S (45.88 g/mol).
A solution contains 85.0 g of NaNO3 and has a volume os 750 mL find the molarity of the solution?
First, convert the mass of NaNO3 to moles using the molar mass of NaNO3. Then, calculate the molarity by dividing the moles of NaNO3 by the volume of the solution in liters. Molarity (M) = moles of solute / volume of solution in liters.

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
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
What volume of a 2 percent erythromycin solution can be made from 15 gm of erythromycin powder?
750ml
What is 5 percent of 750ml?
To find 5% of 750ml, you would multiply 750ml by 0.05 (which is the decimal equivalent of 5%). 750ml x 0.05 = 37.5ml. Therefore, 5% of 750ml is 37.5ml.
What is the concentration of a solution that contains 40 mL of 6M HCl and is diluted to 750mL?
The concentration of HCl is 11,66 g/L.
What does 750ml plus 750ml equal in liters?
750ml + 750ml = 1500ml, which is equal to 1.5 liters.
