Answer:
95.2 - 40.8 = 54.4 g of oxygen
number of moles = mass (g)/ Mr
no. of moles of carbon = 40.8/12 = 3.4
no. of moles of oxygen = 3.4
divide both by smallest value which is 3.4 and you’ll get 1 mole of carbon and 1 mole of oxygen therefore the empirical formula is CO

hope this helps :)
Extensive properties<span>, such as mass and volume, depend on the amount of matter being measured. </span>Intensive properties<span>, such as density and color, do not depend on the amount of the substance present.</span>
I believe that the answer is 11.5

Answer:
The answer to your question is below
Explanation:
Data
Volume 1 = V1 = 3000 l
Temperature 1 = T1 = 30°C
Pressure 1 = P1 = 99 kPa
Volume 2 = ?
Temperature 2 = T2 = 16°C
Pressure 2 = P2 = 45.5 kPa
Process
1.- To find the new volume we need to convert the temperature to °K
T1 = 30 + 273 = 303°K
T2 = 16 + 273 = 289°K
2.- Use the Combined gas law
P1V1/T1 = P2V2/T2
-Solve it for V2
V2 = P1V1T2 / T1P2
-Substitution
V2 = (99 x 3000 x 289) / (303 x 45.5)
-Result
V2 = 85833000 / 13786.5
V2 = 6225.8 l
There are no conversion factor ratios.
