1 mole Si = 28.0855g Si
245g Si x 1mol Si/28.0855g Si = 8.72 moles Si
3,80 g Zn have 0,058 moles.
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 0,253 moles.
573,28 of g of AgCI is equivalent to 4 moles.
1 g silicon is equal to 0,0356 moles.
11 grams of silicon Si equals 0,39 moles.
11 g x 1 mol Si/28.0855 g Si= 0.39 mol Si 205g He x 1mol He/4.002602 g He=51.2 mol He
3,80 g Zn have 0,058 moles.
The formula is: number of moles = g Be/9,012.
Sulfuric acid has a molecualr weight of 98 and so 2.5 moles would weigh 245 g
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
The answer is 0,253 moles.
The answer is 0,4 moles.
The answer is 0,364 moles.
573,28 of g of AgCI is equivalent to 4 moles.
978 g calcium contain 24,4 moles.
