Explanation:
https://brainly.com/question/14608041
The number of atoms= Give mass/molar mass×Avogadro number Therefore number of Mg atoms=48÷24×6.022×10*23
=2×6.022×10*23=12.044×10*2
According to question given monoatomic element contain same number of atom that means numbers of atom =12.044×10*23 and given mass=160g
According to formula= Number of atom= Given mass÷molecular mass×6.022×10*23
12.044×10*23= 160÷M×6.022×10*23
=12.044×10*23×M=160×6.044×10*23
M=80u
