How many moles of a gas sample are in 2.5 l container at 373 k and 203 kpa?

Explanation:

The given data is as follows.

    P = 203 k Pa,           V = 2.5 L

    T = 373 K,                 n = ?

     R = 0.0821 atm L/ K mol

Convert pressure from k Pa to atm as follows.

        = 2.00 atm

Now, using the ideal gas equation we will calculate the number of moles as follows.

                        PV = nRT

                           n =

                              =

                              = mol

                              = 0.163 mol

Thus, we can conclude that number of moles in the given gas sample is 0.163 mol.

explanation:

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
