620 g of mercury is equivalent to 3,09 moles.
159 g of mercury contain 0,792 moles.
620 g of iron contain 11,1 moles.
The answer is 0,4 moles.
978 g calcium contain 24,4 moles.
14,84 g magnesium are equivalent to 0,61 moles.
573,28 of g of AgCI is equivalent to 4 moles.
67,4 g HCl is equivalent to 1,85 moles.
You do not say whether it is grammes or kilogrammes. assuming it to be grams. 1.0 x 10^9 g = 1,000,000,000 g The relative atomic mass of mercury is 200.6 Moles = mass (g / Ar Hence moles(Hg) = 1,000,000,000 / 200.6 = 4985044.865 moles.
3,80 g Zn have 0,058 moles.
The formula is: number of moles = g Be/9,012.
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
The answer is 0,364 moles.
The answer is 0,4 moles.
The answer is 0,253 moles.
978 g calcium contain 24,4 moles.

573,28 of g of AgCI is equivalent to 4 moles.
573,28 of g of AgCI is equivalent to 4 moles.
67,4 g HCl is equivalent to 1,85 moles.
