Question

(i) Calculate the number of electrons which will together weigh one gram.​

Answer 1

heya ..☺️☑

⭕Charge on 1 mole of electrons = (1.602×10-19)×(6.022×1023) = 9.65×104 coulombs. Calculate the total number of electrons present in one mole of methane. (ii) Find (a) the total number and (b) the total mass of neutrons in 7 mg of 14C

I hope its help you ☺️☑❤

Answer 2

Answer:

$here \: is \: ur \: ans....$

(^_^メ)As we know that

Mass of one electron = 9.1× 10^-28 g

1 electron weighs 9.1× 10-^-28 g

So, X electrons will weigh 1 g

X = [1] / [9.1× 10^-28]

= 1.098×10^27 electrons

Therefore 1.098×10^27 electrons together weigh 1g.
