Answer:
In full volume it contain 0.12 moles.
Explanation:
Given data:
Total volume= Vt = 2.9 L
Decreased volume= Vd = 1.2 L
Number of moles of air present in decreased volume= n = 0.049 mol
Number of moles of air in total volume= n = ?
Solution:
Formula:
Vt/ Vd = n (in total volume) /n ( decreased volume)
2.9 L / 1.2 L = X / 0.049 mol
2.42 = X / 0.049 mol
X = 2.42 × 0.049
X = 0.12 mol

Explanation:
<span>Neutrons.
The nucleus of an atom contains two kinds of particles, protons and neutrons. The number of protons determines what element the atom is. Atoms that have the same number of protons but different numbers of neutrons are isotopes of the same element.
For example, if two atoms both have 1 proton in their nuclei, but one atom has 0 neutrons and the other has 1 neutron, both atoms are hydrogen but they are different isotopes of hydrogen.</span>
