Answer to Question #106487 in General Chemistry for Chase

Question

How many molecules are there in 44g of table sugar,glucose

Answer 1

m/M=N/Na;

m- mass;

M- molar mass of ;

N - Quantity of molecules;

Na - Avogadro constant;

N=m*Na/M;

Table sugar is sucrose, it's molar mass is 342

N=44*6.02*10^23/342=7.74502924 × 10^22;

Molar mass of glucose is 180,

N=44*6.02*10^23/180=1.47155556 × 10^23;

Answer:There are 1.47155556 × 10^23 molecules of glucose, or 7.75*10^22 molecules of table sugar
