Answer:

The new volume is 66.3 mL

Explanation:

Boyle's law states that pressure and volume are inversely proportional, and that P1V1=P2V2

P1 = 0.428 atm

P2=1.55 atm

V1 = 240 mL

V2 = ??

(0.428)(240)=(1.55)(V2)

102.72 = 1.55x

x = 102.72/1.55 = 66.27 mL.

What is the molarity of a salt solution made by dissolving 250.0 grams of NaCl in 775 mL of solution?
tester [92]

The molarity of a salt solution made by dissolving 250.0 grams of NaCl in 775 mL of solution is <u>5.52 M</u> .

<u>Explanation:</u>

The molarity of a solution tells one how many moles of <u>solute</u> one can get <em>per liter</em> of solution.One should remember to must convert this volume to liters by using the conversion factor:

1 L = 10³ml

Sodium chloride (NaCl) has a molar mass of 58.44 g per mol , which means that the sample will contain:

   250 \mathrm{g} \times \frac{1 \text { mole of } \mathrm{Nacl}}{58.44 \mathrm{g}}=4.278 \text { mole of } \mathrm{Nacl}

This means that the molarity of the solution will be:

\text {Molarity,c}=\frac{n_{\text {solute}}}{V_{\text {solution }}}=\frac{4.28}{775 \times 10^{-3}}=0.00552 \times 10^{3}=5.52 M
