Question

How many molecules are there in an ideal gas with a volume of 3.97 L at STP?

Answer 1

Answer #1

given volume of ideal gas at stp = 3.97 liter

we know that for ideal gas at stp no of moles of gas = volume in liter/22.414

substitute values to find no of moles of ideal gas present in 3.97 liter volume

no of moles of ideal gas present = 3.97/22.414 = 0.177121442

no of molecules of ideal gas = no of moles x avogadro's number , substitute values

no of molecules of ideal gas present = 0.177121442 x 6.022 x 10²³ = 1.0666253 x 10²³ molecules

ans 1.0666253 x 10²³ molecules of ideal gas are there in 3.97 liter volume at stp
