<span>In commonly table salt is sodium chloride. When table salt is dissolved in water, the solution conducts electricity because sodium chloride is made up of ions, it is called an ionic substance.</span>
Answer:
pressure of the oxygen gas is 7.88atm
Explanation:
Moles of oxygen in cylinder = 2.80 mol
volume=8.58L
temperature=294K
molar gas constant(R)= 0.0821 L atm / (mol K)
The pressure is calculated using ideal gas law:
PV = nRT
making Pressure subject of the formula
P
=
nRT
/V
=
2.80× 0.0821 ×294 /8.58 L
P = 7.88 atm
