Answer:
1.343 atm
Explanation:
We are given the following;
Pressure, p = ?
Volume v = 27 L
Mass of oxygen = 44.9 g
Temperature, T = 315 K
The formular relating all these variables is the equation;
PV = nRT
where R = gas constant = 0.08206 L atm / mole K
To obtain n, we use;
number of moles, n = Mass / molar mass = 44.9 / 32 = 1.403 moles
From the ideal gas equation;
P = nRT / V
P = 1.403 * 0.08206 * 315 / 27
P = 36.27 / 27 = 1.343 atm
Answer:
number of protons and neutrons
Explanation:
Answer:the strength of a bond depends on the amount of overlap between the atoms.
Explanation:the greater the overlap the greater the strength of the bond.
Sound waves are waves of growing larger and smaller, making it seem elastic through substances, such as air.
It is an exothermic reaction
