Answer:
256.52 g/m
Explanation:
Each S has a molecular mass of 32.056 g/mol so multiply that by 8 and you get 256.52.
P1/T1 = P2/T2
125⁰C = 398.15 k
182⁰C = 455.15 k
1.22/398.15 = p2/455.15
p2= 1.39atm
the pressure of the gas be after the temperature change is 1.39 atm

In noble gas notation the simplification in the electron distribution to the orbitals is represented where in of all of the lower filled orbitals up to the closest noble gas is enclosed by its symbols in brackets. The remaining orbitals are written in the usual way.The electronic configuration of Si is 1s22s22p63s23p2.The electronic configuration of Ne is 1s22s22p6. Thus the Noble gas notation of silicon (Si) can be written as [Ne] 3s23p2.</span>
A polar bond is when the charge distribution between two atoms is unequal whereas in a polar molecule the charge distribution is not symmetric
Fluorite is harder than gypsum but softer than apatite. Thus, the correct option is B.
<h3>What is the hardness of any element?</h3>
The hardness of any element may be defined as the capability of a material to oppose the process of deformation and remains in actual shape precisely.
According to the table of hardness scales by Mohs, the increasing order of given hardness of given elements is as follows:
Gypsum < Fluorite < Apatite.
Therefore, Fluorite is harder than gypsum but softer than apatite. Thus, the correct option is B.
