how many moles of cl₂ are in a container with a volume of 7.5 l at stp?
Answer
Explanation:
Step1: Recall STP molar volume
At STP (Standard Temperature and Pressure, 0°C and 1 atm), 1 mole of any ideal gas occupies 22.4 L. So the molar volume ( V_m = 22.4 , \text{L/mol} ).
Step2: Use the formula ( n=\frac{V}{V_m} )
We know the volume ( V = 7.5 , \text{L} ) and ( V_m = 22.4 , \text{L/mol} ). Substitute into the formula: ( n=\frac{7.5}{22.4} ).
Step3: Calculate the result
( n=\frac{7.5}{22.4}\approx0.335 , \text{mol} ).
Answer:
Approximately ( 0.335 ) moles (or more precisely ( \frac{7.5}{22.4}\approx0.335 ) mol)
