hope this helps!
Answer: the new pressure will be 300mmHg
Explanation:
V1 = 30L.
V2 = 50L
P1 = 500mmHg
P2 =?
P1V1 = P2V2
30 x 500 = P2 x 50
P2 = (30 x 500) / 50
P2 = 300mmHg
B because isotopes have the same number of protons but a different number of neutrons
Answer:
Number of atoms = 5.1345 x 10²³
Explanation:
Given:
Mass of sodium = 19.6
Find:
Number of atoms
Computation:
We know that atomic mass of sodium is 22.98
So,
Number of atoms = [Mass of sodium/atomic mass of sodium]Avogadro's number
Number of atoms = [19.6 / 22.98]6.02 x 10²³
Number of atoms = 5.1345 x 10²³
