Question

How many molecules are in 50.000 g of aspartame?

Answer 1

Aspartame stands for C_14H_18N_2O_5

Molar mass:-

• 14(12)+18(1)+2(14)+5(16)
• 168+18+28+80
• 294g/mol

No of moles:-

• Given mass/molar mass
• 50000/294
• 170mol(Approx)

No of molecules:

• No of moles×Avagadro no
• 170×6.022×10²³
• 1023.7×10²³
• 1.02×10²⁶molecules
