200 mL is 0.200 L and 0.90 M means 0.90 moles/L
So, 0.200 L x 0.90 moles/L = 0.18 moles
Molarity = moles of solute/Liters of solution ( 5000 ml = 5 Liters )
Molarity = 90 moles solute/5 Liters
= 18 M
--------------------the most concentrated possible
0.2 mole of solute
The answer is 0,15 moles.,
0.2 moles
o,2 mloes
The molarity of a solution containing 7.0 moles of solute in 569mL of solution is a)81M b)0.081M c)12M D)4.0M The answer is C. 12M 7 x 1000/569 = 12.302
The concentration in moles of a substance in the solution
[2.17/1000]*17.33=0.037mol
The number of moles of a solute per kilogram of solvent. (Apex)
Molarity = moles of solute/Liters of solution Or, for our purposes, Moles of solute = Liters of solution * Molarity Moles Na2CO3 = 10.0 Liters * 2.0 M = 20 moles Na2CO3 --------------------------
The molarity of a solution containing 7.0 moles of solute in 569mL of solution is a)81M b)0.081M c)12M D)4.0M The answer is C. 12M 7 x 1000/569 = 12.302
Some conversion required. (mmolar into mol, or moles into mmol ) Molarity = moles of solute/Liters of solution 100 millimolar = 0.1 M glycine Molarity = moles of solute/Liters of solution manipulate algebraically Liters of solution = moles of solute/Molarity 0.005 mole glycine/0.1 M glycine = 0.05 Liters ( 1000 ml/1 L) = 50 milliliters of solution --------------------------------
Molarity = moles of solute/Liters of solutionOr, for our purposes....,Liters of solution (volume) = moles of solute/MolarityVolume (liters) = 0.150 moles HCl/4.00 M HCl= 0.0375 liters = 37.5 milliliters======================
237.5 mL (200mL if you are keeping track of significant figures). Molarity is moles/liters. To make 900mL of a 2M solution, you need 1.8 moles of solute. There are 1.8 moles of solute in 237.5 mL of 8M solution.
Molarity = moles of solute/Liters of solution Molarity = 5 moles solute/4.5 Liters of solution = 1 M solution ==========
8.42 grams of KOH is equal to 0.15 moles. If the solution has a molarity of 2.26 moles per liter, then there are 66.4 milliliters of solution.
You need to know the moles of solute and the VOLUME of SOLUTION.
The concentration in moles of a substance in the solution
[2.17/1000]*17.33=0.037mol
The number of moles of a solute per kilogram of solvent. (Apex)
Molarity= No. of moles of solute/Volume of solution(in litre) or No. of moles of solute*1000/Volume of solution(in ml)
The number of moles of solute will not change. Too, the molarity of the solution decreases.
