Number of molecules: 8.089×1022 molecules
Explanation
The formula for this question is
Number of molecules
= Number of moles × 6.02x1023
Since,
the number of moles = given mass/formula mass
Here,
Formula mass of sucrose= 342.3 g/mol
Given mass= 46g
Therefore,
The number of molecules = given mass×6.02×1023/
Formula mass
=46×6.02×1023/342.3
=8.089×1022 molecules.
