## How many protons neutrons and electrons does zinc 67 have?

We gots 30 protons, and there must 37 neutrons to make up the mass number, and give the 67Zn isotope. From memory this isotope is approx. 5% abundant (but look it up!). The weighted average mass of all the isotopes is quoted as the atomic mass of zinc on the Periodic Table, 65.4⋅g⋅mol−1 .

8.85

## How many electrons are there in 1 ampere of current?

In practical terms, the ampere is a measure of the amount of electric charge passing a point in an electric circuit per unit time with 6.241 × 1018 electrons, or one coulomb per second constituting one ampere.

Copper

## How many electrons pass through a lamp in one minute if current is 200?

A current of 200 mA is flowing through the lamp. One ampere is the current that flows through the lamp when one coulomb of charge passes in one second. The charge of an electron is 1.602*10^-19 C.

## How many electrons pass through a loop in 2 minutes if the current is 200 MB?

15 × 10¹⁹ electrons pass through a loop in 2 minutes if the current is 200 mA​.

## How many electrons pass through a lamp in 1 minute if the current is 300 million?
