The density of silver is 10.5 g/cm^3. what is the volume of a piece of ag that contains 2.8 × 10^22 atoms?

0.4777 cm³

Explanation:

Molar mass is defined as the mass of 1 mole of the substance.  

The molar mass fo Ag is 107.8682 g/mol

Since, 1 mole of Ag contains 6.022×10²³ molecules of Ag

So,  

6.022×10²³ molecules of Ag has a mass of 107.8682 g

Also,  

1 molecule of Ag has a mass of 107.8682/6.022×10²³  g

2.8×10²² molecules of Ag has a mass of (107.8682/6.022×10²³)×2.8×10²²  g

Mass of 2.8×10²² molecules = 5.0155 g

Given that density = 10.5 g/cm³

Volume = ?

So, volume:  

Volume = 0.4777 cm³

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
