Effusion rate, R, is inversely proportional to the square root of the molar mass, M:
R α 1 / √M
Let Ra be the effusion rate of a gas with molar mass Ma and Rb the efussion rate of a gas with molar mass Mb, then:
Ra / Rb = √ [Mb / Ma]
You know Ra / Rb = 1.82 and Ma = molar mass of N2 = 28.02 g/mol
=> Mb = [Ra / Rb]^2 * Ma = (1.82)^2 * 28.02 g/mol = 92.81 g/mol
Answer: 92.81 g/mol
Answer: Diatomic elements are pure elements that form molecules consisting of two atoms bonded together.
There are seven diatomic elements: hydrogen, nitrogen, oxygen, fluorine, chlorine, iodine, bromine.

Answer:
Limited
Explanation:
For competition to exist within a population or between population, shared or common resources that organisms holds very important must be very limited and scared.
Competition is a struggle between organisms for limited resources in the ecosystem.
- It is an interaction between organisms in which one of them is harmed.
- Competition originates from limited supply of shared or mutual resources among organisms.
- When competition is between organisms from different population, it is called an interspecific competition.
- Competition between organisms within the same population, i.e of the same species is intraspecific competition.
So let's use some equations to represent the data [let R= cost of ring & B= cost of bracelet]
R= B + $ 36 .... (1)
B=
× R ... (2)
By using simultaneous equations to solve for B and R.
Substitute eq. (1) into eq. (2)
B =
× (B + $36)
B =
B +
⇒ B = $48
By substituting value of B into ea (1)
If R = B + $36
R = ($48) + $36
= $84
∴ <span> the total of the two items = R + B
= $84 + $48
</span> = $132
