Question

how mamy grams is equal to 3.48×10^22 atom of tin​

Answer 1

ANS:6.849g/mol

no of moles of tin

=no of atoms/avogadro number

=3.48×10²²/6.022×10²³=0.577×10^-1=0.0577mol

no of moles =mass/molar mass another equation

0.0577mol=mass/118.71g/mol

mass=6.849g

molar mass of tin is 118.71g/mol
