Calculate the volume, in milliliters, occupied by 0.055g of neon gas at STP.

Answer 1

STP

Pressure = 1 atm

Temp = 273K

Molar Mass of Neon = 20.18 g/mol

No. of moles = mass/molar mass

0.055g of Ne = (0.055)/(20.18) moles of Ne

PV = nRT           

= (0.055/20.18) mol x (0.082L*atm/mol*k) x 273K

=0.061L

=61mL 

Volume of Ne (0.055g) at STP is 61mL
