How many grams of Mg0 are produced from 9.7g of MG
1 answer:
Answer= 16g
Explanation:-
Convert grams to moles:
No. of moles= mass/molar mass (Mr)
So,
9.7/24=0.40 mols
Now, multiply the mols with the coefficients of Mg and MgO in this way:
0.40 x 2/2= 0.4 mols
Finally, multiply 0.4 mols with the molar mass (Mr) of MgO:
0.4 x 40= 16g
16 grams of MgO.

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 :
