Question

The mass of an atom of atomic mass 260 amu is

Answer 1

mass = 260 × 1.67 × 10^(-24) gram

Answer 2

Given:

An element of atomic mass 260 amu.

To find:

The mass of an atom of that element.

Formula to be used:

1 mole = $6.022*10^{23}$ atoms.

Step-by-step explanation:

Step 1 of 1

1 mole of an element = Mass of element =  $6.022*10^{23}$ atoms.

260amu =  $6.022*10^{23}$ atoms.

So, 1 atom of that element will have:

$=\frac{260}{6.022*10^{23} } \\\\=43.17*10^{-23}amu \\\\=4.317*10^{-22}amu$

The mass of an atom of atomic mass 260amu is $4.317*10^{-22}amu$.
