Agas system has volume, moles and temperature of 9040 ml, 0.447 moles and -35.50 oc, respectively. what is the pressure in atm?

Answer : The pressure of the gas is, 0.964 atm

Solution : Given,

Volume of gas = 9040 ml = 9.040 L        (1 L = 1000 ml)

Moles of gas = 0.447 moles

Temperature of gas =      

Using ideal gas equation,

where,

P = pressure of the gas

V = volume of the gas

T = temperature of the gas

n = number of moles of gas

R = gas constant =

Now put all the given values in this formula, we get the pressure of the gas.

By rearranging the terms, we get

Therefore, the pressure of the gas is, 0.964 atm

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
