The formula is: number of moles = g Be/9,012.
To find the number of grams in 0.02 moles of beryllium iodide (BeI2), you would first calculate the molar mass of BeI2, which is 262.83 g/mol. Then, you would multiply the molar mass by the number of moles: 0.02 moles * 262.83 g/mol = 5.26 grams of beryllium iodide.
1,24 moles of beryllium is equal to 11,175 g.
The equivalent of 68,3 g Ag is 0,633 moles.
14,84 g magnesium are equivalent to 0,61 moles.
67,4 g HCl is equivalent to 1,85 moles.
573,28 of g of AgCI is equivalent to 4 moles.
First work out the moles So do 36g / 80 (80 is bromine's relative atomic mass number) You have 0.45 M Then, do 0.45 * 6.02*10^23 You get 2.7*10^23, which is your answer
156 g calcium is equivalent to 3,89 moles.
1 g of sodium sulfite is equivalent to 0,0079 moles.
48,5 g sample of CS2 is the equivalent of 0,637 moles.
0,688 g calcium is equivalent to 0,017 moles.
209 g of magnesium silicate is equivalent to 1,91 moles.
