Use the formulae n=m/M
Where,
n - number of mols
m - mass
M - molar mass
Molar mass of Mg = 24
n=202/24 = 8.416

How many grams are in 88.1 moles of magnesium?
If you think to the mass of 88,1 moles of magnesium this is 2141,27 g.
How many grams are in 280 mg?
280mg is 0.28 grams (divide mg by 1,000 to get grams).
How many moles of ions are produced by the dissociation of 1 mole NH4Br?
I assume that is 28.0 grams.28.0 grams MgCl2 (1 mole MgCl2/95.21 grams)= 0.294 moles magnesium chloride==========================Now,One mole Mg 2+ = 0.294 moles Mg 2+ ions=============================2 moles Cl - = 0.588 moles Cl - ions=========================
How many grams are in 524 mg?
524mg is 0.524g (mg divided by 1,000 = grams).
How many moles is 1.346g of Mg?
1.346 grams Mg (1 mole Mg/24.31 grams) = 0.05537 moles magnesium
How many moles in 13.5 grams of magnesium nitrate?
13.5g Mg(NO3)2 x 1 mol Mg(NO3)2/148.3 = 0.0910 mol Mg(NO3)2
How many moles are in 13.2 grams of magnesium?
For this you need the atomic mass of Mg. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Mg= 24.3 grams35.0 grams Mg / (24.3 grams) = 1.44 moles Mg
How do you calculate the number of moles in 4.637 grams in Mg?
For this you need the atomic mass of Mg. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.4.637 grams Mg / (24.3 grams) = .191 moles Mg
How many moles are in 300mg of aspirin?
Aspirins formula is C9H8O4 300 mg Aspirin (1 gram/1000 mg)(1 mole aspirin/180.154 grams) = 0.00167 moles aspirin
How many moles of Mg contain 8.231023 atoms Mg?
8,23.1023 atoms Mg is equivalent to 1,366 moles.
Which equation shows how to calculate how many grams(g) of Mg(OH)2 would be produced from 4 mol KOH. The balanced reaction is mgcl2 plus 2koh mg(oh)2 plus 2kcl?
Two moles KOH for one mole Mg(OH)2; so for 4 moles KOH - two moles Mg(OH)2.And two moles Mg(OH)2 is equal to 116,64 g.
