The density of air under ordinary conditions at 25°C is 1.19g/L . How many kilograms of air are in a room that measures 11.0ft x 11.0ft and has an 8.00 ft ceiling? 1 in. = 2.54 cm (exactly); 1L = 103cm^3

Question

The density of air under ordinary conditions at 25°C is 1.19g/L . How many kilograms of air are in a room that measures 11.0ft x 11.0ft and has an 8.00 ft  ceiling? 1 in. = 2.54 cm  (exactly); 1L  = 103cm^3

anonymous · Answer

(11)(11)(8)=(968ft^3)((12in)^3)/1ft^3)((2.54cm)^3/(1inch^3))(1mL/1 cm^3)(1L/1000ml)= 27400L (3 sig figs) * 1.19= 32600g (1kg/1000g)= 32.6 kg

I did not use your 103cm^3 because its pretty much useless if you can just relate cm^3=mls plus 1000 is a much nicer number.
