It has to be 2 because they are all forms of water

2, because they are all a form of water.. but just in different states of matter depending on their form

A 360. mg sample of aspirin, C9H8O4, (molar mass 180. g), is dissolved in enough water to produce 200. mL of solution. What is t

Gemiola [76]

Answer:

Molarity = 0.01 M

Explanation:

Molarity is used to measure the concentration of a solution. It will be same for the whole solution or a small amount of solution if the solution is homogeneous.

So, <u>Molarity of 200 mL of solution = Molarity of 50 mL of solution</u>

$\mathbf{Molarity = \frac{number \ of \ moles \ of \ solute}{Volume \ of \ solution \ (in \ liters)}}$

$\mathbf{Moles = \frac{given \ mass \ of \ compound}{molar \ mass \ of \ compound}}$

given mass of aspirin = 360 mg = 0.36 g

molar mass of aspirin = 180 g

Volume of solution = 200 mL = 0.2 L

$\mathrm{Mole \ of \ Aspirin = \frac{0.36}{180} = \mathbf{0.002 \ moles}}$

$\mathrm{Molarity = \frac{0.002}{0.2} = \mathbf{0.01 \ M}}$

Therefore, Molarity = 0.01 M

$\Large \text{1)}$

$\textbf{Use the formula and substitute the values}$

$\displaystyle 0.3\ mol/L = \frac{n \ mol}{10 \times 10^{-3}\ L}$

$\textbf{Solve for the number of moles}$

$n = 0.003\ mol$

$\textbf{Calculate final volume }$

$40+10=50\ mL$

$\textbf{Number of moles remains same. Solve for concentration}$

$\displaystyle C=\frac{0.003\ mol}{50 \times 10^{-3}\ L} =0.06\ mol/L$

$\Large \text{2)}$

$\displaystyle DF=\frac{V_f}{V_i}$

$\displaystyle DF=\frac{50}{10}=5$
