Explanation:
Hello,
In this case, by using the ideal gas equation, er can compute the volume of fluorine gas as shown below:
Best regards.
Answer:
4L
Explanation:
To obtain the volume of O2 at stp, first, we need to determine the number of mole of O2.
From the question given above,
Mass of O2 = 5.72g
Molar Mass of O2 = 32g/mol
Number of mole =Mass/Molar Mass
Number of mole of O2 = 5.72/32
Number of mole of O2 = 0.179 mole
Now, we can calculate the volume of O2 at stp as follow:
1 mole of a gas occupy 22.4L at stp.
Therefore, 0.179 mole of O2 will occupy = 0.179 x 22.4 = 4L
Therefore, the volume occupied by the sample of O2 is 4L
Answer:
Hydrogen.
Explanation:
We see in the nucleus that we have 1 proton and 1 neutron.
The number of protons in the nucleus determines which element it is.
Element with 1 proton is the 1st element on the Periodic Table, Hydrogen.
