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

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
