So this is nomenclature.
The name would be Iron (III) Chloride Hexahydrate
Reason why it's Iron (III) is because of the 3 after Cl, if you take FeCl3 apart it's
and Cl^-.
Hexahydrate because hexa = 6 and hydrate=water
The term hydrate would be wrong because that clearly doesn't come first
It would be the anhydrous compound that comes first. The "an" in "anhydrous" means "without". Hydrous=water, so anyhdrous= without water
The part without water is FeCl3. The water is 6H2O
The prefix for the coefficient of water is 6, or hexa, but that's not first in the name
240mL = 0,24L = 0,24 dm³
----------------------------------------
C = n/V
n = 3,5 M × 0,24dm³
n = 0,84 mol NaOH
1 mole NaOH ---------- 40g
0,84 mol ----------------- X
X = 40×0,84
X = 33,6g NaOH

Answer:
The correct answer is = 31.04
Explanation:
The relation between volume, temperature and pressure of a fix amount of a gas can be expressed by the combined gas law:
PV/T = k
It can be written as well as
P1V1/T1 = P2V2/T2
Given:
V1 = 217.6
P1 = 9.011 atm
T1 = 127.8°C = 400.95 K
P2 = 44.9
T2 = 11.9 °C = 285.05
Solution:
Putting value in the formula
V2 = P1V1T2/P2T1
= (217.6*285.05*9.011)/44.9*400.95
V2 = 31.04
Atoms are the smallest form of the substance. examples of atoms are in elemental forms such as copper, helium, silver. Diatomic molecules are made up of identical atoms. Examples are I2.. F2 and Br2. Formula units are those compounds that are made up of two or more elements such as -No2, KMnO4,<span>C3H8, MgCl2, HgBr2, Ba(OH)2</span>
