Question

2.0g of atri-atomic gaseous element was found to occupy a volume of 448 mL at 76cm of Hg and 273 k the mass of the atom is​

Answer 1

Answer:

1 mole is equivalent 22400ml

1/50 mole is equi to 448ml

1/ 50 moles weigh 2 g (from question)

1 mole weighs 2 x 50 g = 100g

since its tri atomic

3 atoms weigh 100g

1 atom weighs 33.334g

these relations can only be used at stp

the condition specified is stp in this question
