For this you need the Atomic Mass of Hg. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.
12.0 moles Hg × 200.6 grams = .0598 grams Hg

Convert 1.2 x 1024 atoms of helium to moles?
How many moles are there in 9.0333x1024 atoms of helium
How many atoms are in 4.7 moles of helium?
2.854x10^24
How many atoms in 3.05 moles of helium?
1 mole has 6.023 x 1023 atoms So, in 3.05 moles there are 18.37 x 1023 atoms
How many moles of heLium are contained in 0.255g of helium?
use this formula, n(He)=m(He)/M(molar mass of He) =0.255G/4.OO =0.06375 moles per gram.
How many moles of He are in 16 g of element?
using the formula: n=m/gfm no. of moles=mass/gfm you take the gram formula mass (gfm) as 4. and given the mass is 16g, both numbers can be substituted into the formula... n=16/4 = 4 the number of moles present in 16g of helium is 4 moles.

How many molecules are in 6.60 moles of He?
The number of helium atoms (not molecules) is 39,7945.10e23.
How many moles of heLium are contained in 0.255g of helium?
use this formula, n(He)=m(He)/M(molar mass of He) =0.255G/4.OO =0.06375 moles per gram.
How many moles of He are in 16 g of element?
using the formula: n=m/gfm no. of moles=mass/gfm you take the gram formula mass (gfm) as 4. and given the mass is 16g, both numbers can be substituted into the formula... n=16/4 = 4 the number of moles present in 16g of helium is 4 moles.
How many moles of helium atoms are there in 2.4 Times 10 to the 24 power of helium atoms?
1 mole = 6.0 x 1023 atomsSo, 4 mole = 24 x 1023 atoms or 2.4 x 1024 atoms
How many molecules are in 9.40 mol He?
9,40 moles helium are equal to 5,6608.10 ex.23 atoms.
How many atoms in 3 moles helium?
For this you need the atomic (molecular) mass of H2. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.3.00 moles H2 × 2.02 = 6.06 grams H2
How many moles of nickel (Ni) atoms are in 125 g Ni?
There are 58.6934 gram in one mole of Ni atoms, so there are125(g Ni) / 58.6934 (g.mol-1 Ni) = 2.13 moles in 125 gram Ni
How many helium atoms are in a helium blimp containing 520 kg of helium?
520 kg = 5.20 X 105 grams. The gram atomic mass of helium is 4.0026; therefore the number of moles of helium in 520 kg is (5.20/4.0026) X 105 or 1.30 X 105. Multiplying this number by Avogadro's Number, 6.022 X 1023, yields the number of atoms, which is about 7.82 X 1028, to the justified number of significant digits.
