Moles of gas = 0.369
<h3>Further explanation</h3>
Given
P = 2 atm
V = 5.3 L
T = 350 L
Required
moles of gas
Solution
Ideal gas Law

Avogadro's law : at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles
moles of O₂ = 45% x 0.369 = 0.166
moles of Ar = 12% x 0.369 = 0.044
moles of N = 43% x 0.369 = 0.159
Answer:
yes
Explanation:
volcanoes have done wonderful things for the earth
- They help cool off the earth removing heat from its interior
- volcanic emissions have produced the atmosphere and the water of the oceans
- volcanoes make islands and add to the continent
volcanoes are necessary because:
fertile is another advantage of volcanic activity."In places like Japan,Indonesia,Philippines,Hawaii,volcanic material mixed in with the soil provides a lot of important nutrients
