a sample of nitrogen gas occupies 120.0 l at 340 k and 2.30 atm. what are the number of moles of nitrogen in the sample?

The number of moles of nitrogen gas is 9.9 moles.

Explanation:

To calculate the mass of bromine gas, we use the ideal gas equation, which is:

PV = nRT

where,

P = Pressure of nitrogen gas = 2.30 atm

V = Volume of nitrogen gas = 120.0 L

n = Number of moles of nitrogen gas = ? mol

R = Gas constant =

T = Temperature of nitrogen gas = 340 K

Putting values in above equation, we get:

Rule of significant figures in case of multiplication and division:

The least number of significant figures in any number of the problem will determine the number of significant figures in the solution.

Here, the least precise number of significant figures are 2. Thus, the number of moles of nitrogen gas is 9.9 moles.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
