Question

A chemist must prepare

275.mL

of

1.00

*M* aqueous sodium chloride

NaCl

working solution. He'll do this by pouring out some

4.71molL

aqueous sodium chloride stock solution into a graduated cylinder and diluting it with distilled water.

Calculate the volume in

mL

of the sodium chloride stock solution that the chemist should pour out. Round your answer to

3

significant digits.

Answer #1

and are the molarity and volume of the stock solution respectively.

and are the molarity and volume of the working solution to be prepared respectively.

The chemist should pour out 58.4 mL of the sodium chloride stock solution.

measure 5 grams of sodium chloride (NaCl) and add to 50 ml of
distilled water in a graduated cylinder. stir the salt. this was a
failed attempt at making a 10% w/v solution. Determine the excess
volume by reading the volume of the graduated cylinder. the number
of ml in excess of 50 represents the volume displaced by the 5g of
dissolved NaCl.
The question for the above information is: What is the actual
percentage of NaCl (w/v)?
Please explain...

A chemist adds 290.0mL of a 2.63/molL sodium chloride NaCl
solution to a reaction flask. Calculate the mass in grams of sodium
chloride the chemist has added to the flask. Be sure your answer
has the correct number of significant digits.

A student is tasked with determining the concentration of an
unknown aqueous sodium chloride (NaCL) solution. A 10.0 mL sample
of the solution weighs 21.6 g. The sample is heated over a flame.
As it is heated, the water solvent evaporates, leaving a dried NaCl
solute residue. After drying, the dish is reweighed and the residue
is found to have a mass of 0.8 grams.
Concentration calculations:
Calculate the mass/mass percent, mass/volume percent, and molarity
of the NaCl solution according...

For an aqueous solution of sodium chloride (NaCl), determine the
molarity of 3.75 L of a solution that contains 147 g of sodium
chloride. M Determine the volume of this solution that would
contain 4.38 moles of sodium chloride. L Determine the number of
moles of sodium chloride in 21.95 L of this solution.

Aqueous hydrochloric acid (HCl) reacts with solid sodium
hydroxide (NaOH) to produce aqueous sodium chloride (NaCl) and
liquid water (H2O). If 2.26g of sodium chloride is produced from
the reaction of 2.2g of hydrochloric acid and 4.3g of sodium
hydroxide, calculate the percent yield of sodium chloride. Be sure
your answer has the correct number of significant digits in it.

A chemist prepares a solution of sodium nitrate
(NaNO3) by measuring out 286. umol of sodium nitrate
into a 450. mL volumetric flask and filling the flask to the mark
with water.
Calculate the concentration in mmol/L of the chemist's sodium
nitrate solution. round your answer to 3 significant digits.

A chemistry student must write down in her lab notebook the
concentration of a solution of sodium thiosulfate. The
concentration of a solution equals the mass of what's dissolved
divided by the total volume of the solution.
Here's how the student prepared the solution:
The label on the graduated cylinder says:
empty weight:2.2g
She put some solid sodium thiosulfate into the graduated
cylinder and weighed it. With the sodium thiosulfate added, the
cylinder weighed 19.440g.
She added water to the...

Suppose
0.332g
of zinc chloride is dissolved in 50.mL
of a
48.0mM
aqueous solution of potassium carbonate.
Calculate the final molarity of chloride anion in the solution.
You can assume the volume of the solution doesn't change when the
zinc chloride is dissolved in it.
Be sure your answer has the correct number of significant
digits.

Noke Lew weighs out 50.0 g of sodium chloride (NaCl) salt. She
adds 300.0 g of water, so her total solution mass equals the salt
plus the water together. Calculate the percent by
mass of NaCl in her solution. Answer to 3 significant
figures with appropriate units.
Doc Inmaking creates another solution by weighing 18.34 mg
(0.01834 g) of Vitamin C with an analytical balance. He dissolves
it in water to a total volume of 250.0 mL using a volumetric...

Suppose 1.35g of iron(II) chloride is dissolved in 250.mL of a
29.0mM aqueous solution of silver nitrate.Calculate the final
molarity of chloride anion in the solution. You can assume the
volume of the solution doesn't change when the iron(II) chloride is
dissolved in it.Round your answer to 3 significant
digits.
