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
The mass of 49,3 mol of the element nickel (Ni) is 2893,6 g.
the m is 34
final is 35
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.
The mass of 2,25 moles of sulfuric acid H2SO4 is 220,677 g.
1 mole Al(CN)3 = 105.03g _ moles = 163g 1 mole Al(CN)3 * 163g / 105.03g 163 moles/105.03 = 1.55 moles
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===============================
163ºF = 72.78ºC
Liters can't be converted to grams. Liters measure volume, while grams measure mass.
163 kg = 163 000 gTo convert from kg to g, multiply by 1000.
Iron is a meta element. Atomic mass of it is 56.
PlutOnium 239 is an element - plutOnium - with an atomic weight of 239.
163g = 5.75oz
156-163 grams
155.9 to 163 grams
Divide by 2.2
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.
163 nanograms = 0.000000163 grams. What exactly are you asking?
Gold is a metal element. There are 79 electrons in a single atom.
