What are the possible values of ml for an electron in a d orbital?

spin [16.1K]

The correct answer for the question that is being presented above is this one: "-2, -1, 0, 1, 2." The possible values of ml for an electron in a d orbital are -2, -1, 0, 1, 2. Since the allowed values for mℓ range from −ℓ to +ℓ, once you know the value for ℓ you know the values for mℓ."

How many molecules are in the substance formula of 2C6H1206 (use coefficients)

FrozenT [24]

Answer: The number of formula units present in 2 moles of $C_6H_{12}O_6$ are $1.2044\times 10^{24}$

Explanation:

Formula units are defined as the number of molecules or atoms present in 1 mole of a compound or element respectively.

According to mole concept:

1 mole of a compound contains $6.022\times 10^{23}$ number of formula units

Here, 2 represents the number of moles of $C_6H_{12}O_6$

We are given:

Moles of $C_6H_{12}O_6$ (glucose) = 2 moles

Number of formula units of $C_6H_{12}O_6=(2\times 6.022\times 10^{23})=1.2044\times 10^{24}$

Hence, the number of formula units present in 2 moles of $C_6H_{12}O_6$ are $1.2044\times 10^{24}$

How many atoms are in 24.6 moles of carbon?

alina1380 [7]

Answer: There are $148.1412\times 10^{23}$ atoms of carbon in the given moles.

Explanation:

We are given 24.6 moles of carbon and we need to find the number of atoms.

According to mole concept:

1 mole of an element contains $6.022\times 10^{23}$ number of atoms.

So, 24.6 moles of carbon will contain $24.6\times 6.022\times 10^{23}=148.1412\times 10^{23}$ atoms.

Hence, there are $148.1412\times 10^{23}$ atoms of carbon in the 24.6 moles of carbon.
