Looks like you already have it.
The osmium with a density of 22.6g/cm3 has a volume in cm3 of 0.965 cm3
The density formula and the procedure we will use is:
ρ = m/v
Where:
- v= volume
- ρ= density
- m= mass
Information about the problem:
Applying the density formula and isolating the volume (v), we get:
ρ = m/v
v = m / ρ
v = 21.8 g / 22.6g/cm3
v = 0.965 cm3
<h3>What is density?</h3>
It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.

The formula that only shows the ratio of one atom to another is called the empirical formula.
Answer:
1. Electronic configuration of sulphide ion S²¯ (18) => 1s² 2s²2p⁶ 3s²3p⁶
2. Ar
Explanation:
1. S²¯ simply indicates that the sulphur atom (S) has gained two extra electrons.
Thus we shall write electron configuration of sulphur (S) and sulphide ion (S²¯) as follow:
The electronic configuration of S²¯
S (16) => 1s² 2s²2p⁶ 3s²3p⁴
S²¯ (18) => 1s² 2s²2p⁶ 3s²3p⁶
2. Determination of the noble gas element that has the same electronic configuration as S²¯.
This is illustrated below:
Sulphur (S) has 16 electrons while the sulphide ion (S²¯) has extra 2 electrons making it to have a total electron of 18. Observing the elements in the periodic table, only Argon has 18 electrons with electronic configuration as:
Ar (18) => 1s² 2s²2p⁶ 3s²3p⁶
Therefore, sulphide ion (S²¯) has the same electronic configuration as Argon (Ar).
Answer:
the Answer is B
Explanation:
If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size. Every stable population has one or more factors that limit its growth. A limiting factor determines the carrying capacity for a species.
hope this helps have a good day :)
