Question

e-Medical : Chemistry
If 224 mL of a triatomic gas has a mass of 1g at
273 K and 1 atm pressure, then the mass of one
atom is -
(1) 8.30 10-23 g
(2) 2.08 x 10-23 g
(3) 5.53 x 10-23 g
(4) 6.24 x 10-23 g
​

Answer 1

I guess that it is option d I it is write plzz text me k

Answer 2

HELLO CUTIE HERE IS YOUR ANSWER❤️

Moles of gas = 224ml/22400ml =0.01 moles Moles = mass / molar mass 0.01 = 1 / molar mass Thus, molar mass = 100g Mass of one atom = molar mass/ NA As the gas is triatomic so it will be

Molar mass/ NA ×3

Putting the values in above formula

100/6.023×3

=5.53×10^-23
