What is the volume of a balloon containing 0.75 moles of gas at STP?

V = 16.81 L

Explanation:

Given data:

Number of moles = 0.75 mol

Temperature = standard = 273 K

Pressure = 1 atm

Volume of balloon = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will rearrange the formula.

V = nRT/P

V = 0.75 mol ×0.0821 atm.L/mol.K ×273 K / 1 atm

V = 16.81 atm.L/ 1 atm

V = 16.81 L

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

increased stability in the completion of fluorine's outer shell.
