you need to do a unit conversion first you need to find the molar mass of the element you do that by adding the Atomic Mass (on Periodic Table) of the element or compound so in this case if the chemical symbol is just Ni then the molar mass is 58.69 if it was Ni2 then you would add 58.69 +58.69 and the molar mass would be 117.38... then you have your unit conversion 1 mole of Ni = 58.69g
20.7 moles of Ni * __ 58.69g____ = 1214.88grams
1 1 mole of N.i

How many moles of Al(CN)3 are in 163 grams of the compound?
To find the number of moles of Al(CN)3 in 163 grams, you need to first calculate the molar mass of Al(CN)3. The molar mass of Al = 26.98 g/mol, C = 12.01 g/mol, N = 14.01 g/mol. Add these together with the appropriate subscripts for the compound to get the molar mass of Al(CN)3. Then, divide the given mass (163 g) by the molar mass to find the number of moles.
What is the molar mass of H2CO3?
1.00794 (H) + 126.90447 (I) = 127.91241 g/mol Even though hydrogen is 1p + 1e, adding protons and electrons does not equal the total mass of an element, because we know energy has mass and that is difficult to calculate ( E = mc ^2), although that answer should suffice.
What mass of KOH is needed to make 400mL of 725 M KOH?
I assume you mean 7.25 M KOH, but the process is the same anyway.Molarity = moles of solute/Liters of solution ( 400 ml = 0.4 Liters )7.25 M KOH = X moles KOH/0.4 Liters= 2.9 moles KOH (56.108 grams/1 mole KOH)= 163 grams potassium hydroxide needed===============================
What is the mass of oxygen in 250 g of sulfuric acid H2SO4?
To find the mass of oxygen in sulfuric acid (H2SO4), we first need to calculate the molar mass of the compound. The molar mass of H2SO4 is 98.08 g/mol. The molar mass of oxygen in H2SO4 is 4 * 16 = 64 g/mol. To find the mass of oxygen in 250 g of H2SO4, we can use the proportion: (64 g / 98.08 g) * 250 g = 161.3 g of oxygen.
