Asoft drink contains 46 g of sugar(sucrose c12h22o11) how many sugar molecules are present?

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.  

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

there is none because earth is stationary and flat.
