Question

How many moles are present in 4.7 liters of argon gas as STP

Answer 1

0.2098mole

Step-by-step explanation:

we know ,

1 mole (gas) =22.4 liters [in STP]

so,

22.4 liters argon gas = 1 mole

4.7 liters argon gas = (4.7/22.4)mole

=0.2098mole

Answer 2

Answer:

0.21mol Ar (g)

Step-by-step explanation:

To convert from litres to moles at STP we must divide the amount of litres by 22.4.

4.7 / 22.4 = 0.21mol Ar (g)
