Al2(CrO4)3 = 401.9 grams per mole
There are 1825.6 g in a 14.5 moles Lithium permanganate
<h3>
Further explanation</h3>
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass :

moles of Lithium permanganate = 14.5
Lithium permanganate (LiMnO4) MW=125.9 g/mol, so mass :

Answer:
Atoms X and Atom Y are isotope is right answer
Answer:
The correct option is A
Explanation:
Water from a river is used for many activities in a community. These activities could include (but not limited to) tourism, drinking for animals, local transport, irrigation for nearby farming, recreation (as in swimming), habitat for some living organisms among others. Rivers are not limited by what limits the influence of oceans such as taste (it's saltiness, which cannot be used in farming also) and wave current.
