Answer: n = 3.0 moles

V = 60.0 L

T = 400 K

From PV = nRT, you can find P

P = nRT/V = (3.0 mol)(0.0821 L-atm/K-mol)(400 K)/60.0L

P = 1.642 atm = 1.6 atm (to 2 significant figures)

Answer:

P = 1246.4 mmHg

Explanation:

assuming ideal gas:

PV = RTn

∴ R = 0.082 atm.L/K.mol

∴ V = 60 L

∴ T = 400 K

∴ n gas = 3 mol

⇒ P = RTn / V

⇒ P = ((0.082 atm.L/K.mol)(400 K)(3 mol))/(60 L)

⇒ P = (1.64 atm)×(760 mmHg/atm)

⇒ P = 1246.4 mmHg

Answer:

Final calculated molarity of the unknown acid be lower than the actual concentration.

Explanation:

Volume required unknown acid = V= 25.0 mL

Volume actually measure was more than V that is = V'

V' > V

Molarity of the solution is the moles of compound in 1 Liter solutions.

$Molarity=\frac{\text{Mass of compound}}{\text{Molar mas of compound}\times Volume (L)}$

As we can see from the formula that molarity is inversely proportional to the volume of the solution.

$Molarity\propto \frac{1}{Volume}$

Molarity of solution decreases with increase in volume
Molarity of solution Increases with decrease in volume.

We have added more volume than required which will be increase the volume of solution and the molarity of the solution will lower than the actual value.

Answer:

They all have the same number of protons but different numbers of neutrons.

Explanation:

Elements will always have the same number of protons no matter the isotopes. Isotopes only change the number of neutrons. Silicon will always have 14 protons. So silicon-28 has 14 protons and 14 neutrons. Silicon-29 has 14 protons and 15 neutrons. Silicon-30 has 14 protons and 16 neutrons.
