Hello!

A student requires 2.00 L of 0.100 M NH4NO3 from a 1.75 M NH4NO3 stock solution. What is the correct way to get the solution ?

Measure 114 mL of the 1.75 M solution, and dilute it to 1.00 L.  

Measure 114 mL of the 1.75 M solution, and dilute it to 2.00 L.  

Measure 8.75 mL of the 1.75 M solution, and dilute it to 2.00 L.

Measure 8.75 mL of the 0.100 M solution, and dilute it to 2.00 L.

We have the following data:

M1 (initial molarity) = 0.100 M (or mol/L)

V1 (initial volume) = 2.00 L

M2 (final molarity) = 1.75 M (or mol/L)

V2 (final volume) = ? (in L or mL)

Let's use the formula of dilution and molarity, so we have:

M_{1} * V_{1} = M_{2} * V_{2}

0.100 * 2.00 = 1.75 * V_{2}

0.2 = 1.75\:V_2

1.75\:V_2 = 0.2

V_2 = \dfrac{0.2}{1.75}

\boxed{\boxed{V_2 \approx 0.114\:L}}\:\:or\:\:\:\boxed{\boxed{V_2 \approx 114\:mL}}\:\:\:\:\:\bf\green{\checkmark}

Answer:

Measure <u><em>114 mL</em></u> of the 1.75 M solution, and dilute it to 2.00 L.

Answer: Measure 114 mL of the 1.75 M solution, and dilute it to 2.00 L.

Explanation:

The number of moles in the solution will remain same on dilution and thus according to Molarity Equation:

M_1V_1=M_2V_2

M_1= molarity of first solution

V_1= Volume of first solution

M_2= molarity of second solution

V_2= Volume of second solution

0.1\times 2.00L=1.75M\times V_2

V_2=0.114L=114ml

Thus 114 ml of 1.75 M solution is taken and the volume is diluted to 2.0 L to make 0.100 M solution.

Answer:

Here's what I get  

Explanation:

CH₃CH₂CH₂CH₂CH₂CH₃ —  hexane

CH₂=CHCH₂CH₂CH₂CH₃ —  hex-1-ene is the preferred IUPAC name (PIN). 1-Hexene is accepted

CH₃C≡CCH₃ —  but-2-yne (PIN); 2-butyne is accepted

CH₃CH(CH₃)CH₂CH₂CH₃ — 2-methylpentane

CH₃CH₂CHCICH₂CH₃ — 3-chloropentane

What causes water molecules to be attracted to each other?
Fiesta28 [93]
This polarity makes water molecules attracted to each other. The oxygen-hydrogen bond in the alcohol molecule is also polar. But, the carbon hydrogen bonds in the rest of the alcohol molecule are nonpolar. In these bonds, the electrons are shared more or less evenly.

Do equal volumes of the same gas at the same temperature and pressure contain equal numbers of molecules (number of moles)?
tresset_1 [31]

Answer:Therefore, there must be a direct relationship between these volumes of gases and the number of molecules they contain. Avogadro's law says that: Equal volumes of different gaseous substances, measured under the same pressure and temperature conditions, contain the same number of molecules.

Explanation:I hope it works for you.
