Question

Calculate the no. Of electrons in1.8 gm of glucose

Answer 1

Hey, here is ur answer

First calculate the mole if solutes
solute=glucose

No. of moles= Weight of Solute in gm/ Molecular weight

1.8/180 =.01 moles

No.of molecules= 6.22*10^23*.01= 6.22*10^21

No.of electrons in 1 molecules of glucose=96

Then after, multiply 96* 6.22*10^21

hope u got it

Answer 2

1 mole of glucose(C₆H₁₂O₆=180grams) contains
(6 x 6) + (12 x 1) + (6 x 8) = (96 x Avogadro number) of e⁻

1.8 grams means 0.01 moles of glucose.

That is, 
           1 mole of glucose has 96 x Avogadro  number of electrons
 
 0.01 moles of glucose has "0.01 x 96 x Avogadro  number of electrons"
                                        =  0.96 x 6 x 10²³ electrons
                                        = 5.76 x 10²³ electrons are present in 1.8 grams                                                  of glucose.
