thanks!!!

Calculate the density of sulfur hexafluoride gas at 703 torr and 23°C. density is mass/volume so how do i get those from what i am given? also ) Calculate the molar mass of a vapor that has a density of 6.735 g/L at 11°C and 743 torr.

Calculate the number of molecules in a deep breath of air whose volume is 2.68 L at body temperature, 37°C, and a pressure of 743 torr (b) The adult blue whale has a lung capacity of 5.0 103 L. Calculate the mass of air (assume an average molar mass 28.98 g/mol) contained ...

thanks! for b i used that equation and got the volume to be .400 buts its wrong. do i use the presure from a or do i just use 1atm?

science
that was my answer for letter a and i did all of those conversions first and i still got that anwerrs which is wrong. can you do the problem and tell me what you get?

science
i got 1.28 but its wrong

science
how do i ansewr this question? An aerosol spray can with a volume of 400. mL contains 2.25 g of propane gas (C3H8) as a propellant (a) If the can is at 31°C, what is the pressure in the can? (b) What volume would the propane occupy at STP? (c) The can's label says that...

find the measures bc and ac
