Question

Number of molecules in 90g of sugar

Answer 1

Answer:

The formula of sugar is :- C12H22011,

Explanation:

SO,

Molecular weight of the compound=

C=12;H=1;O=16;

So according to the compound molar mass will be:

12×12+1×22+16×11;

144+22+176;

=>342;

Therefore no. of moles=342/90;

3.8 approx 4

So number of molecules will be

4×6.023×10²³ molecules
