What volume will 6.745g of neon gas occupy at standard temp and pressure?

Explanation:

It is given that mass of neon is 6.745 g and molar mass of neon is 20 g/mol.

Hence, calculate the number of moles as follows.

            No. of moles =

Putting the given values into the above formula as follows.

          No. of moles =

                                =

                                = 0.34 mol

Also, at standard conditions value of temperature is 298 K and pressure is 1 atm.

So, putting the values into ideal gas equation and calculate the value of volume as follows.

                          PV = nRT

                  V = 8.31 L

Thus, we can conclude that volume of given neon gas is 8.31 L.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
