If a shell can hold a maximum of 32 electrons, what is the value of n?
olga2289 [7]
<span>Begin by classifying which energy level, and indirectly principal quantum number, n, resembles to the N shell. no. of orbitals =n2 In your case, the fourth energy level will contain n=4⇒no. of orbitals= 4^2=16 The number of subshells is given by the principal quantum number. no. of subshells=n In your case, the fourth energy level will have no. of subshells = 4 this is the answer to check: the fourth energy shell will can hold a thoroughgoing of no. of electrons=2⋅42=32 e−</span>

The volume of a diamond is found to be 2.8 ml. what is the mass of the diamond in carats?
Helen [10]

Answer:

49.14 carat.

Explanation:

From the question given above, we obtained the following data:

Volume of diamond = 2.8 mL

Mass of diamond (in carat) =.?

Next, we shall determine the mass of diamond in grams (g). This can be obtained as follow:

Volume of diamond = 2.8 mL

Density of diamond = 3.51 g/mL

Mass of diamond ( in grams) =?

Density = mass /volume

3.51 = mass /2.8

Cross multiply

Mass of diamond (in g) = 3.51 × 2.8

Mass of diamond (in g) = 9.828 g

Finally, we shall Convert 9.828 g to carat. This can be obtained as follow:

1 g = 5 carat

Therefore,

9.828 g = 9.828 g /1 g × 5 carat

9.828 g = 49.14 carat.

Therefore, the mass of the diamond in carat is 49.14 carat.
