What is the mass in grams of 1 liter of nitrogen gas?
AlladinOne [14]

Assuming the volume of the gas is measured at standard temperature and pressure, Then one mole of the Gas would occupy 22.4 liters.

Therefore, 1 liter is 1/224 moles

one mole of nitrogen 14 is 14

Therefore 1 liter of the nitrogen weighs 1/224×14

0.0625 grams

How many total electrons can enter the set of 3p orbitals?<br> a. 3<br> b. 10<br> c. 2<br> d. 6
Sliva [168]

Answer:

For n=3 and l=1=p

It is 3p-orbital.

Magnetic quantum number m

l

have values from -l to +l and total of 2l+1 values.

Forl=1, m

l

values are:

m

l

=−1,0,1 for l=1; total m

l

values =3= Number of orbitals

Each orbital can occupy maximum of two electron

Number of electrons =2×3=6

Thus 6 electrons will show same quantum number values of n=3 and l=1.

Number of elements with last electron in 3p orbitals = 6

Which of the following BEST states the Law of Conservation of Matter? *
Nookie1986 [14]

Answer:

A. The total mass of the reactants in a reaction equals the total mass of the product(s).

Explanation:

The law of conversation of matter tells us that in a chemical reaction, matter is never created or destroyed, it's simply converted from one form to another. So the mass of reactants should always equal the mass of the products in a chemical reaction.
