Answer:
0.924 g
Explanation:
The following data were obtained from the question:
Volume of CO2 at RTP = 0.50 dm³
Mass of CO2 =?
Next, we shall determine the number of mole of CO2 that occupied 0.50 dm³ at RTP (room temperature and pressure). This can be obtained as follow:
1 mole of gas = 24 dm³ at RTP
Thus,
1 mole of CO2 occupies 24 dm³ at RTP.
Therefore, Xmol of CO2 will occupy 0.50 dm³ at RTP i.e
Xmol of CO2 = 0.5 /24
Xmol of CO2 = 0.021 mole
Thus, 0.021 mole of CO2 occupied 0.5 dm³ at RTP.
Finally, we shall determine the mass of CO2 as follow:
Mole of CO2 = 0.021 mole
Molar mass of CO2 = 12 + (2×16) = 13 + 32 = 44 g/mol
Mass of CO2 =?
Mole = mass /Molar mass
0.021 = mass of CO2 /44
Cross multiply
Mass of CO2 = 0.021 × 44
Mass of CO2 = 0.924 g.

Hello!
My argument: Which is better a Ps4 or an Xbox 1
The Ps4 is a better all-round console. The PS4 costs $100 less but has less games than the Xbox 1. The Xbox 1 now came up with dual compatible games. This means that certain games can now run on the Xbox 1 and the Xbox 360. The overall winner is really undetermined. The controller for Xbox has more quicker response time and is specifically built to be an extremely comfortable in your hands. Unlike the PS4 which their controller is built for nothing they really didn't do anything to theirs. Although the console comparisons are the same. The hard drive for the Xbox is non- removable meaning that if you want the hard drive. you would have to break the Xbox to get it . Unlike the Ps4 when you can take it out easily and switch it with any console and still have your data. I am an Xbox fan since for ever but I think that the two consoles are built the same.
Hope it helps!
Answer:
When popcorn is popped, liquid inside the kernel is changed to steam. Pressure from the steam builds up inside the kernel. When the pressure reached a critical stage the kernel pops turning itself inside out. This is a physical change.
