Use this:
C = mol / vol
so CNaCl = 4.2(mol) / 0.450(L) = 9.33 (mol/L) = 9.3 M

What is the molarity of a solution of 95 grams of NaOH to 450 ml of water?
95g NaOH * 1 mol NaOH/ = 2.375 mol NaOH 40g NaOH Molarity (M) = mol / L M = (2.375) / (0.450) M = 5.28
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?
Assuming the same relation of dissolved drug, 76.5g. 450/100*17
If 120 mL of a 1.0 M glucose solution is diluted to 450.0 mL what is the molarity of the diluted solution?
(126)(1.3)=163.8 divide 163.8 by 450 = .364 which is the answer
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
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

How many grams are equal to 450 milligrams?
Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters) 5M C6H12O6 = moles C6H12O6/0.450 liters = 2.25 moles C6H12O6 (180.156 grams/1 mole C6H12O6) = 405.351 grams of glucose ( you do significant figures )
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
