15.9643 gramns are in 2.3 moles of lithium
Answer:
The volume of the sample of the gas is found to be 12.90 L.
Explanation:
Given pressure of the gas = P = 1.10 atm
Number of moles of gas = n = 0.6000 mole
Temperature = T = 288.15 K
Assuming the volume of the gas to be V liters
The ideal gas equation is shown below

Volume occupied by gas = 12.90 L
Decrease . because the natural ph of blood is 7.35 the neutral ph , diseases such as emphysema disrupts the ph causing it to become acidic .
N= number of molecules
n= 2.3x10^23/6.022x10^23
= 0.381 mol
Now,
M= molar mass in g/mol
m= mass in grams
m=nxM
=0.381 molx137 g/mol
= 52.197g
So, the correct answer should be C
