Thomas poured 25 mL of 0.60 M HCl into a large bottle. He then added enough water so that the new (diluted) concentration was 0.
Molodets [167]

Answer:

The answer to your question is 150 ml

Explanation:

Data

Volume 1 = 25 ml

Concentration 1 = 0.6 M

Volume 2 = ?

Concentration 2 = 0.1 M

Formula

            Volume 1 x Concentration 1 = Volume 2 x Concentration 2

Solve for Volume 2

             Volume 2 = (Volume 1 x Concentration 1)/Concentration 2

Substitution

             Volume 2 = (25 x 0.6) / 0.1

Simplification

            Volume 2 = 15 / 0.1

Result

            Volume 2 = 150 ml

Enter your answer in the provided box. A person's blood alcohol (C2H5OH) level can be determined by titrating a sample of blood
Annette [7]

<u>Answer:</u> The mass percent of alcohol in blood is 0.183 %

<u>Explanation:</u>

To calculate the moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}

Molarity of Cr_2O_7^{2-} solution = 0.05961 M

Volume of solution = 35.46 mL = 0.03546 L   (Conversion factor:  1 L = 1000 mL)

Putting values in above equation, we get:

0.05961M=\frac{\text{Moles of }Cr_2O_7^{2-}}{0.03546L}\\\\\text{Moles of }Cr_2O_7^{2-}=(0.05961mol/L\times 0.03546L)=2.11\times 10^{-3}mol

The given chemical reaction follows:

16H^+(aq.)+2Cr_2O_7^{2-}(aq.)+C_2H_5OH(aq.)\rightarrow 4Cr^{3+}(aq.)+2CO_2(g)+11H_2O(l)

By Stoichiometry of the reaction:

2 moles of dichromate ions react with 1 mole of ethanol.

So, 2.11\times 10^{-3}mol of dichromate ions will react with = \frac{1}{2}\times 2.11\times 10^{-3}=1.06\times 10^{-3}mol

  • To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Moles of ethanol = 1.06\times 10^{-3}mol

Molar mass of ethanol = 46.07 g/mol

Putting values in above equation, we get:

1.06\times 10^{-3}mol=\frac{\text{Mass of ethanol}}{46.07g/mol}\\\\\text{Mass of ethanol}=(1.06\times 10^{-3}mol\times 46.07g/mol)=0.0488g

  • To calculate the mass percent of ethanol in blood, we use the equation:

\text{Mass percent of ethanol}=\frac{\text{Mass of ethanol}}{\text{Mass of blood plasma}}\times 100

Mass of blood plasma = 26.60 g

Mass of ethanol = 0.0488 g

Putting values in above equation, we get:

\text{Mass percent of ethanol}=\frac{0.0488g}{26.60g}\times 100=0.183\%

Hence, the mass percent of alcohol in blood is 0.183 %

Why does a permeable rock weather chemically at a fast rate?
ki77a [65]
<span>Water soaks into it easily and during freeze-thaw cycles would be more likely to break apart because of the water freezing and thawing inside the rock. The water freezes and expands inside the rock, causing the surface to break off in flakes from the pressure of the expanding ice inside.</span>
