Answer: I'm guessing but I think this is the answer and also what I put in mine sorry if wrong
Explanation: I think it's "B.- Slightly Acidic" srry if it's too late-
Answer:
Some formulas for calculating mole are
Mole = Mass/ Molar mass
Mole = no of particles / avogadros constant
NB : no of particles can be no of atoms , no of ions , or no of molecules 2. Avogadros number or constant = 6.02 times 10 ^23
so we will be using the second formula
Mole = no of particles / avogadros constant
Mole = 5.03 x 10 ^23/6.02 x10^23
Mole = 8.355x10^45
hope it helps :)
Explanation:
Mols is shorthand for molarity, a unit of measurement corresponding to moles/liter. A mole is just a number for example “ a dozen”. Mole is also spelled mol in chemistry so they do mean the same.

Answer:
<u>We are given:</u>
v1 = 3.2 L v2 = x L
p1 = 822 torr OR 1.08 atm p2 = 2.33 atm
t1 = t2 = 284 k
<u></u>
<u>From the Ideal gas equation:</u>
PV = nRT
Since the number of moles (n), universal gas constant (R) and Temperature (T) are constant
PV = k (where k is a constant)
it can also be written as:
P1V1 = k --------------------------(1)
Similarly,
P2V2 = k (where k is the same constant as before)----------(2)
<u>Solving for V2:</u>
From (1) and (2):
P1V1 = P2V2
Replacing the variables
1.08 * 3.2 = 2.33 * x
x = (1.08 * 3.2)/2.33
x = 1.5 L (approx)
Therefore, the final volume of the solution will be 1.5L
NO2 is a covalent compound
