A sealed flask contains Ne, Ar, and Kr gas. If the total pressure in the flask is 3.782 atm, the partial pressure of Ne is 0.435

spin [16.1K]

Answer:

$P_{Ar}=1.734atm$ = partial pressure of Ar

Explanation:

Acccoding to dalton's law of partial pressure total pressure of system is equal to alzebraic sum of all partial pressure.

$P_{total} =P_{Ne}+P_{Ar} +P_{Kr}$

$P_{total}=3.782atm$

$P_{Ne}=0.435 atm$

$P_{Kr}=1.613atm$

$P_{Ar}=P_{total}-P_{Ne}-P_{Kr}$

$P_{Ar}=3.782-0.435-1.613$

$P_{Ar}=1.734atm$ =partial pressure of Ar

How many miles of silver nitrate do 2.888 x 10^15 formula units equal?

Furkat [3]

Answer: 4.8x10^-9 mol

Explanation:

1mole of Silver nitrate contains 6.02x10^23 molecules

Therefore, Xmol of silver nitrate will contain 2.888x10^15 molecules i.e Xmol of silver = 2.888x10^15/6.02x10^23 = 4.8x10^-9 mol
