What grade are you in because im in eighth grade and that is hard
i cant even look up the answer online
From a stock solution of 3.00 m nitric acid, 9.391 ml of stock solution is needed to create a 0.161 m nitric acid solution, which has a total volume of 175 ml of the diluted solution.
A chemical reagent is present in vast quantities as a stock solution. It has a uniform concentration. Examples of typical stock solutions in laboratories are nitric acid and hydrochloric acid. These play a critical role in creating the titration-related solution preparations.
We know the formula for dilution type problems
M1 VI = M2 V 2
Where,
M, = initial molarity
V , = initial Volume
M2 = final molarity
V 2 = final Volume
Hene given -
M, = 3.00 M
VI = ?
M2 = 0.161M
V 2 = 175 ml
Accordingly ' MI V1 = M2 V 2
V1 =
V1= (0.161M*175ml)/ 3.00M
v1 = 9.391
The required volume of Stock solution is 9.391ml.

The name of the compound is Thorium (IV) Iodide and formula of the compound ThI₄.
<h3>What is Molecular Formula ?</h3>
The chemical formula that gives total number of atoms of each element in one molecule of a compound is called Molecular Formula.
<h3>What is Atomic Number ?</h3>
The number of proton which is used to separate one element from the other element is called Atomic Number.
here the atomic of the element Q is 90 and the atomic number of R is 53. The element Q is Thorium. Symbol of Thorium is Th. The element R is Iodine. Symbol of Iodine is I.
The valency of thorium is +4 and valency of Iodine is -1. So the formula of the compound is ThI₄.
Thus from the above conclusion we can say that The name of the compound is Thorium (IV) Iodide and formula of the compound ThI₄.

It's any of the almost spherical concentric regions of matter that make up the earth and it's atmosphere, as the lithosphere and hydrosphere.
Hope this helps... If you could, could you mark my answer as brainliest? I'm trying to level lol
Answer:
0.o75 mol Ti = 4.5x10∧22
2.10 mol CO2 = 1.26x10∧24 molecules
