A sample 0. 100 moles of a gas is collected at at STP . 2.24 is the volume of the gas in liters.
The STP means standard temperature and pressure.
At STP,
Temperature = 0 °C =273 K
Pressure = 1 atm
We get value of volume by using ideal gas equation,
PV = nRT
- P is the pressure of the gas = 1 atm
- V is the volume occupied by the gas = ?
- n is the number of the moles = 1 mole
- T is the temperature of the gas = 273 K or 0 °C
- R universal gas constant = 8.31 J/ mole × K
Calculation,
Since, one mole of a gas occupy 22.4 L volume at STP
So, for 0.1 mole volume occupy = 22.4L × 0.1 mole/1 mole = 2.24L

#SPJ4
Scientist rely on their estimates when they cannot obtain on exact numbers
Here's the first one
- The ellipse becomes a straight line
- here's the second one they converge
They don't converge when the eccentricity ratio is zero, instead the diverge.
So "the foci converge is not true"
Hope this helps!!
The answer is F, or Fluorine.
Because of Fluorine's high reactivity, it is never found in nature.
The answer is F.
