Question

EXERCISES
Calculate the number of electrons which will together weigh one gram.​

Answer 1

Answer:

the number of electrons which will weigh one gram is 10 to the power -3 /9.11*10 to the power -31= 1.098*10 to the power 27.

Answer 2

Answer:

The number of electrons which will weigh 1 g is 9.11×10−3110−3=1.098×1027 .

Mass of one mole of electrons is 9.11×10−31×6.023×1023=5.486×10−7kg.

Charge of 1 mole of electrons is 1.602×10−19×6.023×1023=9.647×104 C.
