If 5.00 g helium gas is added to a 1.00 l balloon containing 1.00 g of helium gas, what is the new volume of the balloon? assume no change in temperature or pressure. enter your answer in the box provided. l

Explanation:

The given data is as follows.

                  = 5 g,         = 1 L

                  = 1 g,         = ?

No. of moles of helium present in 5 g helium gas are as follows.

                   No. of moles =

                                         =  

                                         = 1.25 mol

No. of moles of helium present in 1 g helium gas are as follows.

                 No. of moles =

                                         =  

                                         = 0.25 mol

According to the ideal gas equation, PV = nRT. And, since temperature and pressure are held constant. Therefore,

                              = 0.2 L

Thus, we can conclude that the new volume of the balloon is 0.2 L.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
