A bag of potato chips contains 585 mL of air at 20.0 C and a pressure of 765 mmHg. Assuming the bag does not break, what will be
Scorpion4ik [409]

Answer:

volume = 972.23ml

Explanation:

using general gas law

P1V1/T1 = P2V2/T2

765 x 585/293 = 443 x V2/282

1527.39 =443 x V2/282

1527.38 x 282 = 443 x V2

430695.78 = 443 x V2

V2 = 430695.68/443

V2 = 972.23mL

To make a sarurated solution, 36 g of sodium chloride is dissolved in 100 g of water at 293 k . Find its concentration at this t
nexus9112 [7]

Answer:

The answer is "26.47\%"

Explanation:

Sodium chloride  solute mass=36 \ g

Solvent water mass=100\ g

Calculating the solution mass = Solute mass  + solvent mass

                                                  = 36\ g +100\ g\\\\ = 136\ g\\\\

Calculating the percentage of concentration:

= \frac{solute\ mass}{solvent\ mass} \times 100\\\\=\frac{36\ grm}{136\ grm} \times 100\\\\=0.2647 \times 100\\\\=26.47 \%
