A balloon is filled to a volume of 18.9L at a temperature of 27.1ºC. If the pressure in the balloon is measured to be 2.20 atm, how many moles of gas are contained inside the balloon?

The number of moles of gas in balloon is 1.69 moles

Explanation:

To calculate the number of moles of gas, we use the equation given by ideal gas which follows:

where,

P = pressure of the gas = 2.20 atm

V = Volume of the gas = 18.9 L

T = Temperature of the gas =

R = Gas constant =

n = number of moles of gas = ?

Putting values in above equation, we get:

Hence, the number of moles of gas in balloon is 1.69 moles

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

where are the choice options?
