How many moles of nitrogen gas are in a flask with a volume of 0.25 L at a pressure of 2.96 atm and a temperature of 300 K

The number of moles of nitrogen gas is 0.030 moles

Explanation:

To calculate the number of moles of nitrogen, we use the equation given by ideal gas which follows:

where,

P = pressure of the nitrogen gas = 2.96 atm

V = Volume of the gas = 0.25 L

T = Temperature of the gas = 300 K

R = Gas constant =

n = number of moles of nitrogen gas = ?

Putting values in above equation, we get:

Hence, the number of moles of nitrogen gas is 0.030 moles

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
