Smaller, there are many human and systematic errors that can alter the amount of product that can be obtained.
Answer: There are 0.024 moles of gas are present in the container.
Explanation:
Given: Temperature = 
= (25 + 273) K = 298 K
Pressure = 1.7 atm
Volume = 345 mL (1 mL = 0.001 L) = 0.345 L
Formula used is as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T= temperature
Substitute the values into above formula as follows.
Thus, we can conclude that there are 0.024 moles of gas are present in the container.
Answer:
The answer to your question is Tb = 100.768°C
Explanation:
Data
Tb = ?
moles of KBr = 3
mass of water = 2000 g
Kb = 0.512 C/m
Process
1.- Calculate the molality of the solution
molality = moles of solute/mass of solvent (kg)
-Substitution
molality = 3/2
-Result
molality = 1.5
2.- Calculate ΔT
ΔTb = Kbm
-Substitution
ΔTb = (0.512)(1.5)
-Result
ΔTb = 0.768
3.- Calculate the boiling point, the boiliing point of pure water is 100°C
ΔTb = Tb - Tb(solvent)
-Solve for Tb
Tb = Tb(solvent) + ΔTb
-Substitution
Tb = 100 + 0.768
-Result
Tb = 100.768°C
