According to the atomic model given by Rutherford, the atom is a dense, and tiny positively charged core known as the nucleus, which is enveloped by lighter and negatively charged electrons. An electron refers to a stable subatomic particle comprising a negative charge, which is found in all the atoms.  

The following are the correct statements:  

1. The electrons are situated in orbits or shells around the atom.  

2. The electrons are traveling so fast, that it becomes almost impossible to locate their precise locations.

Which of the following samples will have the greatest volume at STP?
Tamiku [17]

Answer:

Option b. 22 g of He will have the greatest volume at STP

Explanation:

In order to determine the volume, we apply the Ideal Gases Law equation:

P . V = n . R . T

V = n . R . T / P

R, T and P are the same in all the situation we must define n (number of moles).

The one that has the greatest number of moles will have the greatest volume at STP

22 g of Ne . 1mol / 20.1 g = 1.09 moles of Ne

22g of He . 1mol / 4 g = 5.5 moles of He

22 g of O₂ . 1mol / 32g = 0.68 moles of O₂

22 g of Cl₂ . 1mol / 70.9 g = 0.31 moles of Cl₂
