Answer:
<h2>The answer is option e</h2>
Explanation:
To find the number of moles we must first find the molar mass of LiCL
From the question
mass = 0.550g
M(Li) = 6 Cl = 35.5
Molar mass of LiCL = 6 + 35.5 = 41.5 g/mol
Then we use the formula
where
n is the number of miles
m is the mass
M is the molar mass
So we have
We have the final answer as
<h3>0.0130 mol</h3>

Answer:
234.35 °C
Explanation:
Given data:
Volume of balloon = 125000 mL
Moles of oxygen = 3 mol
Pressure = 1 atm
Temperature = ?
Solution:
Formula:
PV = nRT
P = Pressure
V = volume
n = number of moles
R = ideal gas constant
T = temperature
Volume of balloon = 125000 mL × 1 L /1000 mL
Volume of balloon = 125 L
Now we will put the values:
Ideal gas constant = R = 0.0821 atm.L/mol.K
PV = nRT
T = PV/nR
T = 1 atm × 125 L/ 0.0821 atm.L/mol.K × 3 mol
T= 125 /0.2463 /K
T = 507.5 K
K to °C
507.5 K - 273.15 = 234.35 °C
