Answer:
This solution has a volume of 98.4 mL
Explanation:
Step 1: Data given
Molarity of AgClO4 solution = 1.27 mol/L
Number of moles AgClO4 = 125 mmol = 0.125 mol
Molar mass of AgClO4= 207.32 g/mol
Step 2: Calculate volume of the 1.27 M solution
Molarity = moles / volume
Volume = moles / molarity
Volume = 0.125 moles / 1.27 mol /L
Volume = 0.0984 L = 98.4 mL
This solution has a volume of 98.4 mL
Answer:
Given,
P1=760 torr
T1=21°C
T2=250°C
P2=?
Solution,
According to Gay-Lussac's Law or Third Gas Law,
P1T2=P2T1
760×250=21×P2
P2=9047 torr
9047 is the pressure of the gas at 250 degree Celsius.
