What size container do you need to hold 0.0459 mol of N2 gas at stp

Answers

The size of the container needed to hold the gas is 1.03 L

Data obtained from the question

  • Number of mole (n) = 0.0459 mole
  • Pressure (P) = STP = 1 atm
  • Temperature (T) = STP = 273 K
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Volume (V) =?

How to determine the volume

The volume of the container needed can obtained by using the ideal gas equation as illustrated below:

PV = nRT

Divide both side by P

V = nRT / p

V = (0.0459 × 0.0821 × 273) / 1

V = 1.03 L

Therefore, the size of the container needed is 1.03 L.

Answer:

The size of the container needed is 1,03 liters

Explanation:

We use the formula PV=nRT. The STP conditions correspond to 1 atm of pressure and 273 K of temperature.

PV=nRT V=(nRT)/P

V= (0,0459 mol x 0,082 l atm/ K mol x 273K)/1 atm= 1,0275174 liters

Which is a mixture?potassium metal

chlorine gas

potassium chloride

potassium and chlorine

Answers

Answer : The correct option is potassium and chlorine.

Explanation :

Mixture : It is a substance which is made by the combination of two or more things in such a way there is no chemical reaction occurs.

For example : Sand and water, oil and water, milk and chocolate, etc.

  • Potassium is a metal.
  • Chlorine is a gas.
  • Potassium chloride is a compound.
  • Potassium and chlorine is a mixture.
A mixture is potassium and chlorine. A mixture is a combination of pure substances that have no definite composition. It may be either a homogenous or heterogeneous.
