A mixture consisting of 0.120 mol N2, 0.018 mol O2, 0.112 mol CH4, and an unknown amount of CO2 occupies a volume of 9.04 L at 25°C and 1.17 atm pressure. Assuming that the gases all behave as ideal gases, how many moles of CO2 are there in this sample?

answer; economic order quantity;

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i
