Answer:
6^3 I believe.
Explanation:
If it's wrong it may be 6^2 because you should square it, but I think it's 6^3
The volume of a gas is defined by the volume of its container.
However, given the number of moles, and standard temperature and pressure, you can use the Ideal Gas Law to calculate the volume.
Answer:
b. 1.20x10^24 molecules NH3
Explanation:
At STP, one mole of gas has a volume of 22.4 dm^3
1 dm^3 = 1 L
Therefore,
44.8 L = 44.8 dm^3
This means that there are 2 moles of NH3 in 44.8 L at STP.
number of molecules = number of moles times avogadro's number
Avogadro's number = 6.02x10^23
Numner of molecules = 2 x 6.02x10^23
= 1.204x10^23 molecules
Answer: 3.2 x 10^21
Explanation:
One molecule of oxygen gas (O2) contains two atoms of oxygen.
So, 1.6 X 10^21 molecules of oxygen gas will contain...
1.6 x 10^21 x 2 = 3.2 X 10^21 atoms of oxygen
