The system will move in such a way that it must restore its original state or simply to cancel the effect of its disturbance.

1.00 L of a gas at STP is compressed to 473mL. What is the new pressure of gas?

Ratling [72]

Hello!

1.00 L of a gas at STP is compressed to 473 mL. What is the new pressure of gas?

We have the following data:

Vo (initial volume) = 1.00 L

V (final volume) = 473 mL → 0.473 L

Po (initial pressure) = 1 atm (pressure exerted by the atmosphere - in STP)

P (final pressure) = ? (in atm)

We have an isothermal transformation, that is, its temperature remains constant, if the volume of the gas in the container decreases, so its pressure increases. Applying the data to the equation Boyle-Mariotte, we have:

$P_0*V_0 = P*V$

$1*1 = P*0.473$

$1 = 0.473\:P$

$0.473\:P = 1$

$P = \dfrac{1}{0.473}$

$\boxed{\boxed{P \approx 2.11\:atm}}\:\:\:\:\:\:\bf\green{\checkmark}$

Answer:

The new pressure of the gas is 2.11 atm

How many grams of NaCl are needed to prepare 50.0 grams of 35.0% of salt solution?

nevsk [136]

Answer:

17.5 g

Explanation:

Given data

Mass of solution to be prepared: 50.0 grams

Concentration of the salt solution: 35.0%

The concentration by mass of NaCl in the solution is 35.0%, that is, there are 35.0 grams of sodium chloride per 100 grams of solution. We will use this ratio to find the mass of sodium chloride required to prepare 50.0 grams of a 35.0% salt solution.

$50.0gSolution \times \frac{35.0gNaCl}{100gSolution} = 17.5gNaCl$

The ph of a substance equals −log[h+] where [h+] is the concentration of hydrogen ions. [h+] for tomato juice is 10−4. what is t

Wittaler [7]

The Ph of tomato juice is calculated as follows

Ph = -log (H+)

if H+ ion concentration is 10^-4

Ph is therefore = -log (10^-4) =4

the tomato juice has a Ph of 4
