Three chromium bromides are known: CrBr2, CrBr3, CrBr4.
* CrBr2: 247, 5985 mg of Cr per 1 g of bromide
* CrBr3: 179,9145 mg of Cr per 1 g of bromide
* CrBr4: 141,1209 mg of Cr per 1 g of bromide
The molar mass of chromium (Cr) is approximately 51.996 g/mol. Therefore, the mass of one mole of chromium is about 51.996 grams.
you take the number of moles given (1.002) and mulitply it by chromium's Atomic Mass (52) and get your answer.
1.002 * 52= 52.104 grams
Chromium is a metal element. Atomic mass of it is 52.
1.47 X 10^24 atoms of chromium (1 mole Cr/6.022 X 10^23)(52.0 grams/1 mole Cr)
= 127 grams of chromium
Chromium is a metal element. Atomic mass of it is 52.
atomic mass 51.996 amu
51.996 grams
This is some easy math: chromium (Cr, #24) has an atomic mass of 52 grams per mole (from the periodic table). According to the Avogadro constant, 1 mole of any substance contains 6.02x1023 representative particles. So, 52g of Cr is 1 mole, and contains 6.02x1023 atoms.

One mole of gold has a greater mass than one mole of silver because gold has a higher atomic mass compared to silver. The atomic mass of gold is around 197 grams per mole, whereas the atomic mass of silver is around 108 grams per mole.
The mass of one mole of a substance is equal to its molar mass, which is numerically equivalent to the atomic or molecular weight in grams. For example, one mole of carbon has a mass of 12 grams, one mole of water (H2O) has a mass of 18 grams, and one mole of sodium chloride (NaCl) has a mass of 58.5 grams.
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.

This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
32 grams, you can find the mass of one mole of any element by looking at its atomic mass eg chlorine has Atomic mass of 35.5 so the mass of one mole of chlorine is 35.5 grams.

HI, A MOLE IS MOLECULAR MASS. MOLECULAR MASS OF SODIUM IS 23. HENCE, 1.22 MOLE = 1.22*23 = 28.60
28.086 g + 12.011 g = 40.097 g
The atomic mass, in grams, is the mass of one mole of atoms.
