Use this:

C = mol / vol

so CNaCl = 4.2(mol) / 0.450(L) = 9.33 (mol/L) = 9.3 M

The molarity of a solution is calculated by dividing the number of moles of solute by the volume of the solution in liters. In this case, since the volume is 450 ml (0.45 L) and the number of moles of NaCl is 4.2 mol, the molarity would be 4.2 mol / 0.45 L = 9.33 M.

What is the molarity of 32.0 of NaOH in 450 of NaOH solution?

I assume you mean 32.0 grams of NaOH and 450 milliliters of NaOH. Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters ) get moles of NaOH 32.0 grams NaOH (1 mole NaOH/39.998 grams) = 0.800 moles NaOH Molarity = 0.800 moles NaOH/0.450 liters = 1.78 Molar NaOH

What is the molarity of a solution of 95 grams of NaOH to 450 ml of water?

To calculate the molarity, you first need to convert the grams of NaOH to moles using the molar mass of NaOH (40 g/mol). Then, you divide the moles of NaOH by the volume of solution in liters (450 ml = 0.45 L) to get the molarity. Molarity = moles of NaOH / volume of solution in liters Moles of NaOH = 95 g / 40 g/mol = 2.375 mol Molarity = 2.375 mol / 0.45 L = 5.28 M


What is the molarity of 9. 33 g Na2S in 450 mL solution?

Molarity = moles/litermoles = 9.33 g Na2S x 1 mole/78 g = 0.1196 molesliters = 450 ml x 1L/1000 ml = 0.45 Lmolarity = 0.1196 moles/0.45 L = 0.266 M = 0.27 M (2 sig figs)


If 17g of a drug is dissolved in 100mL how many grams are dissolved in 450ml?

To find out how many grams are dissolved in 450mL, you can use a proportion based on the given information. The drug concentration is 17g/100mL, so you can set up the proportion: 17g/100mL = x/450mL. Cross multiply and solve for x to find the amount of drug dissolved in 450mL.


If 120 mL of a 1.0 M glucose solution is diluted to 450.0 mL what is the molarity of the diluted solution?

To find the molarity of the diluted solution, you can use the formula: M1V1 = M2V2. Plug in the values: (1.0 M)(120 mL) = M2(450.0 mL) to find M2. Solving for M2, you get M2 = (1.0 M)(120 mL) / 450.0 mL = 0.27 M.

What volume of a 6.0Mol solution do you need to make a 450ml solution with a molarity of 2.5M?

187.5 ml of the 6.0 Molar solution mixed with (I assume) 262.5 ml water will produce 450ml of 2.5M.This can be solved with a system of equations. Assign variables x and y to be the quantities of the two respective liquids, say x for the 6.0M solution and y for the water.We know one equation is x + y = 450ml.Also, if I make an equation of Molarity x qty, I get:6.0x + 0y = 450*2.5which is 6x = 1125So my system of equations is:6x = 1125x + y = 450From here you should be able to easily solve for x from the first equation, then substitute for x into the second equation to find y.You should really get this whole mixing thing down before you embark upon consumption of alcoholic beverages. Just a little advice. :) 1 shot Everclear does not equal 1 shot JD. Why? Different %alcohol by volume! Sorry about that tangent...


What is the molarity of HCl if 450 mL of 2.3 M HCl is diluted to 1250 mL?

You mean if the amount of solvent is changed from 450 mL to 1250 mL without changing the amount of HCl?2.3 M = (x mol/0.450 L) x = 0.450 x 2.3 = 1.035 mol HClx M = (1.035 mol/1.25 L) = 0.828 M

How many molecules are there in 450 grams of NaSO4?

To find the number of molecules in 450 grams of NaSO4, we first need to calculate the number of moles using the molar mass of NaSO4 (142.04 g/mol). Then, we can use Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of molecules in the calculated moles.
