Answer:
The correct answer is option B
Explanation:
![$Molarity=\frac{Weight}{Molecular \,weight} \frac{1000}{V(in \, ml)}](https://tex.z-dn.net/?f=%24Molarity%3D%5Cfrac%7BWeight%7D%7BMolecular%20%5C%2Cweight%7D%20%5Cfrac%7B1000%7D%7BV%28in%20%5C%2C%20ml%29%7D)
Given values,
Molarity of ![$FeCl_3=0.100M$](https://tex.z-dn.net/?f=%24FeCl_3%3D0.100M%24)
Volume of solution, ![$V=250ml$](https://tex.z-dn.net/?f=%24V%3D250ml%24)
Molecular weight of ![$FeCl_3=162.2$](https://tex.z-dn.net/?f=%24FeCl_3%3D162.2%24)
Substituting this values in Molarity formula, we get
![$0.1=\frac{weight}{162.2} \times\frac{1000}{250} $\\$\Rightarrow 16.22=weight\times4$\\$\Rightarrow weight=\frac{16.22}{4} $\\$\therefore weight=4.06g$](https://tex.z-dn.net/?f=%240.1%3D%5Cfrac%7Bweight%7D%7B162.2%7D%20%5Ctimes%5Cfrac%7B1000%7D%7B250%7D%20%24%5C%5C%24%5CRightarrow%2016.22%3Dweight%5Ctimes4%24%5C%5C%24%5CRightarrow%20weight%3D%5Cfrac%7B16.22%7D%7B4%7D%20%24%5C%5C%24%5Ctherefore%20weight%3D4.06g%24)
Most <span>scientists </span>suggest diminishing carbon dioxide outflows. Less carbon dioxide in the climate would be relied upon to diminish the quantity of biotic calculates biological systems. A biotic element is any living part that influences the number of inhabitants in another living being, or the earth. This incorporates creatures that expend the life form and the living nourishment that the living being devours.
Answer:
by using this formula you will get it
Explanation:
number of mole = number of particles÷ Avogadro's number
n=3.51×10^23÷ 6.02×10^23
n = 0.58 moles
It should be noted that when Brian first sorted out his thoughts, the first thing that he thought would happen next is that he would probably be rescued that day.
It should be noted that in Chapter 5 of Hatchet, Brian wakes up in the forest and then, he realized that he was desperately thirsty.
When Brian first sorted out his thoughts, he figured this was the first day after the crash and that he would probably be rescued that day. He believed that he was going to wither up and die if he doesn't get anything that he'll drink.
