Calculate the number of moles of a gas that is present in a 7.55 l container at 45°c, if the gas exerts a pressure of 725mm hg. enter your answer in the box provided. mol

The number of moles of gas present is 0.276 moles

Explanation:

To calculate the number of moles of gas, we use the equation given by ideal gas:

PV = nRT

where,

P = Pressure of the gas = 725 mm Hg

V = Volume of the gas = 7.55 L

n = number of moles of gas = ?

R = Gas constant =

T = Temperature of the gas =

Putting values in above equation, we get:

Hence, the number of moles of gas present is 0.276 moles

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
