There are 0.1428 moles of helium in 3.2 Liters of helium at the STP.
Step 1: Identifying the appropriate formula to apply.
Molar gas volume stp is 22.4 L
This means that the 1 mole of a Gas is equal to 22.4 Liters.
Step 2: identifying given volume of the gas.
In this case we have 3.8 Liters of the helium.
Step 3: Applying formula to get the answer.
1 mole = 22.4 Liters
?= 3.2 Liters.
By cross multiplication we have the
3.2/22.4 × 1 = 0.1428 moles.
Step 4 : The number of moles.
There are 0.16964 moles of helium in the 3.4 Liters of helium at STP.
