Question

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

Answer 1

Answer:

1027electrons

Explanation:

1.098×1027electrons weigh 1 gram

Answer 2

Explanation:

(i) Number of electrons which together weigh one gram.

We already know the mass of an electron which is 9.11×10−31kg=9.11×10−28g9.11×10−31kg=9.11×10−28g

1 electron weighs 9.11×10−28g9.11×10−28g

X electrons weigh 1 g.

We have to calculate x.

x×9.11×10−28g=1×1⇒x=19.11×10−28g=1.098×1027x×9.11×10−28g=1×1⇒x=19.11×10−28g=1.098×1027

1.098×10271.098×1027electrons weigh 1 gram.
