If a 2.50 liter container is filled with ne gas at a pressure of 650 mm hg and at 25°c, what mass of ne is in the container?

1.76 g is the mass of Ne is in the container.

Explanation:

We use the equation given by ideal gas which follows:

where,

P = pressure of the gas = 650 mm Hg

V = Volume of the gas = 2.50 L

T = Temperature of the gas =

R = Gas constant =

n = number of moles of Ne gas = ?

Putting values in above equation, we get:

Also, molar mass of Ne = 20.1797 g/mol

So,

1.76 g is the mass of Ne is in the container.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
