An auditorium measures 43.0m × 18.0m × 15.0m. the density of air is 1.20 kg/m3. what is the volume of the room in cubic feet? (do not input units. note that 1m = 3.28ft)
my answer 43x18x15 = 11,610 m^3 11,610m3 * 3.28ft m = 38,080.8 ft when i used this number i got it incorrect and it said for me to use less figures

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
