Question

A soft drink contains 46 g of sugar(sucrose C12H22O11) how many sugar molecules are present?

Answer 1

8.092752363 ×10 to the power of 22

Answer 2

Answer

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.
