A sample of gas is kept at a temperature of 300 k, a volume of 1.45L, and a pressure of 3.00 kPa. How many moles of has are in the sample

the number of moles of the gas is 0.00174 mol.

Explanation:

Given;

temperature of the, T = 300 K

volume of the gas, V = 1.45 L

Pressure of the gas, P = 3.0 kPa

The number of moles of the gas is calculated using Ideal gas equation, as follows;

PV = nRT

Where;

n is number of moles of the gas

R is the ideal gas constant, = 8.315 L.kPa/mol.K

n = PV / RT

n = (3 x 1.45) / (8.315 x 300)

n = 0.00174 mol.

Therefore, the number of moles of the gas is 0.00174 mol.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
