Recently, there has been much concern about pollution in the home from radon, a

radioactive gas whose elemental molar mass is 222 g/mol. The Environmental

Protection Agency say that a level or radon of 3.6 X 10-11 giL of air is unhealthy. At

this level, how many moles of radon would there be in a living room whose volume is

2455 L? How many atoms is this?

Its suppose to be 3.6e-11g/L

what i ended up doing was got 3.6e-11g/L(2455L)= 8.838x10^-8g/2455L

then, 8.838x10^-8g converted them into moles then into atms. right or wrong?

Yes, that's right.
