5.8 moles of nitrogen gas are needed to pressurize the air bag.
<h3>What's the expression of Ideal gas equation?</h3>
- Ideal gas equation is PV=nRT
- P= pressure, V = volume, n= no. of moles of gas, R= universal gas constant, T = temperature of the gas
<h3>What's the no. of moles of nitrogen present in a 60L air bag at 2.37 atm pressure and 25°C temperature?</h3>
- P= 2.37 atm, V = 60L, R= 0.0821 L-atm/mol-K, T = 25°C = 298K
- n= PV/RT
= (2.37×60)/(0.0821×298)
= 5.8 moles
Thus, we can conclude that 5.8 moles of nitrogen gas are needed to pressurize the air bag.

Answer:
Both equilibrium price and quantity will increase.
Explanation:
An increase in the income of video game players will surely lead to an upward shift in the supply and demand curve. This shift in the supply and demand curve would affect the equilibrium price and quantity positively leading to a correspondent increase in the equilibrium price and quantity.
Explanation:
modern quantum mechanics explains these periodic trends in properties in terms of electron shells. the filling of each shell corresponds to a row in the table
Answer:
Bone homeostasis involves multiple but coordinated cellular and molecular events. Two main types of cells are responsible for bone metabolism: osteoblasts (which secrete new bone), and osteoclasts (which break bone down).
