Agas under a pressure of 74 mmhg and at a temperature of 75°c occupies a 500.0-l container. how many moles of gas are in the container?

Answer : The number of moles of gas present in container are 1.697 mole.

Explanation :

Using ideal gas equation,

where,

P = pressure of gas = 74 mmHg = 0.097 atm

conversion used : (1 atm = 760 mmHg)

V = volume of gas = 500.0 L

T = temperature of gas =

n = number of moles of gas = ?

R = gas constant = 0.0821 L.atm/mole.K

Now put all the given values in the ideal gas equation, we get the number of moles of gas in the container.

Therefore, the number of moles of gas present in container are 1.697 mole.

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
