how does the number of atoms in a 27.5-gram manganese ring compare to the number in a chromium ring of the same mass?

Sagot :

The number of atoms will be more for chromium ring than for mangnese ring.

A mole is 6.022*10^23 atoms/molecules. The SI unit for the amount of substance is a mole and it is represented by “mol”.

The mass of manganese ring is 27.5 grams.

Molar mass of manganese is 54.9 gram/mol.

n=m/M

n=27.5/54.9

n=0.500 mol

The number of atoms of manganese ring can be calculated as follows:

Number of atoms= 6.022*10^23 * 0.500=3.01*10^23 atoms.

The mass of chromium ring is 27.5 grams.

Molar mass of chromium is 51.9 gram/mol.

n=m/M

n=27.5/51.9

n=0.529 mol

The number of atoms of manganese ring can be calculated as follows:

Number of atoms= 6.022*10^23 * 0.529=3.19*10^23 atoms.

Therefore, the number of atoms will be more for chromium ring than for mangnese ring.
