How many atoms are in a mole of Hg?
Avogadro’s Number: Avogadro’s number gives us the number of entities present in 1 mole of anything: 6.022 × 1023 Hg atoms in 1 mole Hg.
How many atoms are there in Hg?
For example, there are 6.022 x 1023 atoms in one mole of Hg.
How many atoms does 1 mole of mercury have?
one mole of mercury (Hg) contains 6.0*10^23 atoms of Hg. one mole of Hg has a mass of 201 grams.
How many moles of atoms are there in 40.1 g Ca?
Divide the mass of element in grams by its molar mass in gram per mole to obtain moles of the element. The molar mass of Ca is 40.08 g/mol. Calculate the moles present in 40.1 g Ca as follows: Thus, the moles of Ca are 1.00 mol.

How many atoms are in a mole of iron?
1 mole = 6.02 x 1023 atoms 1 mole = atomic mass (g) 5. Convert 9500g of iron to number of atoms in the sample. 9500 g Fe 1 mole 6.02 x 1023 atoms = 1.0 x 1026 atoms 55.8g 1 mole.
Which is bigger a mole or a HG?
The answer is 200.59. We assume you are converting between grams Hg and mole. You can view more details on each measurement unit: The SI base unit for amount of substance is the mole. 1 grams Hg is equal to 0.0049852933845157 mole.
• The mass of an atom in amu is numerically the same as the mass of one mole of atoms of the element in grams. • One atom of sulfur has a mass of 32.07 amu; one mole of S atoms has a mass of 32.07 g. Mass of 1 H atom: 1.008 amu x 1.661 x10-24 g/amu = 1.674 x10-24 g Mass of 1 mole of H atoms: 1.674 x10-24g/H atom x 6.022 x1023H atoms = 1.008 g
How many grams are in a mole of carbon?
We know that the molar mass of 1 mole of carbon is equal to 12. It means that 12 grams per mole
