We can use gas laws to determine the number of moles of gas in a 168L tank at STP (Standard Temperature and Pressure).

Step-by-step explanation:

At STP, one mole of gas occupies 22.4 L. Therefore, to find the number of moles (n) of gas in a 168L tank, we can use the following formula:

n = V / VM

where V is the volume of the gas and Vm is the molar volume at STP.

Substituting the values:

n = 168 L / 22.4 L/mol

Calculating the result:

n ≈ 7.5 mol

Answer: Therefore, approximately 7.5 moles of gas are in a 168L tank at STP.
