Answer:

.025 moles

Explanation:

Be Cl2   is beryllium chloride

Be = 9.0121 gm/mole

Cl = 35.45 gm mole

   Be Cl2 = 79.91 gm/mole

2 gm / 79.91 gm/mole = .025 moles

An electron in a hydrogen atom has orbital quantum number l = 7. how many possible values of the magnetic quantum number ml coul
MA_775_DIABLO [31]

A total of 15 magnetic quantum values are possible.

<h3>What is a Magnetic quantum number?</h3>

One of the four quantum numbers that describe an electron's position in relation to the nucleus is its magnetic quantum number.

Between spin and azimuthal quantum numbers, the magnetic quantum number comes in third on the list. The electron is positioned in one of the various orbitals formed by the division of the subshells (such as s, p, d, and f). It specifies the spatial direction of an orbital of certain energy (n) and form (I). The number of orbitals in each subshell is given as 2+1, where is the azimuthal quantum number. We can determine the orbital in each sub-shell using that method.

We are aware that there are between -l and +l conceivable magnetic quantum numbers.

Here l = 7

Thus, the range of magnetic quantum numbers will be -7 to +7.

Thus, the magnetic quantum numbers are as follows:

-7, -6, -5, -4,-3,-2,-1, 0, 1,2,3,4, 5, 6,7

This opens up a total of 15 magnetic quantum numbers.
