Answer:
25.1 g is the mass of chlorine in the sample
Explanation:
P . V = n . R . T
We apply the Ideal Gases Law to solve the excersise.
We need to convert the T°C to T°K → 37°C + 273 = 310K
We replace data: 3 atm . 3L = n . 0.082 L.atm /mol.K . 310K
9 atm.L / (0.082 L.atm /mol.K . 310K) = n → 0.354 moles
We convert the moles to mass, to reach the answer
0.345 mol . 70.9g / 1mol = 25.1 g
Answer:A
Explanation: because i saw the sheet
There is two iron atoms.
The formula iron oxide is Fe2O3 F e 2 O 3 therefore there would be two. Hope this helps. :)
-The mole is appropriate only for counting things that are very small.
-One mole is a very large number of something.
-A molecule of water is much smaller than a grain of sand.
