14,400 gallons of water can be filtered by the new water filter invented by the company.
It is given that the filter can process 10 gallons of water per minute.
So In an hour:
10 gallons per minute x 60 minutes = 600 gallons in 1 hour.
And in a day:
24 hours x 600 gallons per hour = 14,400 gallons in 24 hours.
Hence, 14,400 gallons of water can be filtered.

Answer: argon (Ar)
Ar, Z=18 => 1s2 2s2 2p6 3s2 3p6
The 3 level shell has 8 electrons. The element with one more electron, need to start a new shell to arrange for the last electron.
Argon is a noble gas. Its group in the periodic table is 18. All the noble gases have the last shell full, which conferes them a high stability and low reactivity.
1 mol ---- 2,02 g
4 mol ---- x g
x = 4 mol × 2,02 g / 1 mol = 8,08 g
Answer : The mass of this sample is 8,08 g.

Answer: 3.86x10^24 molecules
Explanation:
From Avogadro's hypothesis, we understood that 1mole of any substance contains 6.02x10^23 molecules.
This means that 1mole of H2O contains 6.02x10^23 molecules.
Therefore, 6.42 moles of H20 will contain = 6.42 x 6.02x10^23 = 3.86x10^24 molecules
