Explanation:
The number of orbitals in the sublevels are given below:
Sublevels Orbitals
s 1
p 3
d 5
f 7
a. ls - 1 orbital
b. 5s - 1 orbital
c. 4d - 5 orbitals
d. 4f - 7 orbitals
e. 7s - 1 orbital
f. 3p - 3 orbitals
g. Entire 5th principal energy level : for s, p , f
1 + 3 + 5 + 7 + 9 = 25
h. 6d - 5
The significant figures will be 1.
As, weight of acetylsalicylic acid = 0. 4 g
We obtain 400 mg when we convert 0.4g of acetylsalicylic acid to mg.
So, 400 milligrams are worth 0.4 grams when converted to grams.
There is just one significant figure because 0 before a decimal is not significant i.e. 4.
<h3><u>What are significant figures?</u></h3>
The digits of a number that have relevance in relation to the measurement's resolution are known as significant figures. Additionally known as significant figures in chemistry. All experimental measurements are subject to some degree of uncertainity.

Energy levels are considered orbitals.
Answer:
37.7 atm
Explanation:
Using the relation;
(P + an^2/V^2) (V - nb) = nRT
(P + an^2/V^2) = nRT/(V - nb)
a = 0.0341 atm dm^2 Mol^2
b = 0.0237 dm/mol
P = nRT/(V - nb) - an^2/V^2
P = [4.3 * 0.082 * 325 / (3.6 - (4.3 * 0.0237))] - (0.0341 * (4.3^2))/(3.6^2)
P = 114.595/(3.498) - 0.0487
P = 37.7 atm
