is **193000 Coulomb**. Thus, the correct option is (B).

## How much electricity is required in coulombs for the oxidation of 1 mole of h2 o2 o2?

**3×102C**.

## How many coulombs of electricity are required for reduce 1 mole?

**9.** **65×106C**.

## How many coulombs are in an electric charge?

The coulomb (symbol: C) is the International System of Units (SI) unit of electric charge. Under the 2019 redefinition of the SI base units, which took effect on 20 May 2019, the coulomb is exactly **1/(1.602176634×10 ^{−}^{19}) elementary charges**.

## How much charge in Coulomb is present in 14g of n3?

Selina – Chemistry – Class 7

For 1 g-ion. 1 g-ion = (weight in grams of sum of atomic weight of atoms making the ion.) Here N^3- has 14 amu so 1g-ion 14 gm. Therefore 6.022 × 10^23 ions has = 6.022 × 10^23 ×1.6 ×10^-19 × 3 C = **2.89 × 10^5 C**.

## How many coulombs are required for reduction of 0.2 moles of cr2o7?

**1×96500 C**.

## What is the charge of 1 mole of electrons?

Charge on a single electron is 1.6 x 10^-16 Coulomb. There are 6.02 x 10^23 electrons per mole. So we get the charge on one mole of electrons as (1.6 x 10^-16) x (6.02 x 10^23) = **96500 C** which is also called 1 Faraday.

## How many coulombs are required to produce 50g of Al from molten al2o3?

Thus, **535575 C** of electricity will be needed to deposit 50g of Aluminium.

## How much charge is required for the reduction of 1 mole of CU?

∴ For the reduction of 1 mole ofCu+ ions to Cu, charge required is **2F**.

## How many moles of platinum will be deposited on the cathode?

Thus, **0.2 moles** of Platinum is deposited on Cathode.

## What is coulomb equal to?

The coulomb, also written as its abbreviation ‘C’, is the SI unit for electric charge. One coulomb is **equal to the amount of charge from a current of one ampere flowing for one second**. One coulomb is equal to the charge on 6.241 x 10^{18} protons. The charge on 1 proton is 1.6 x 10^{–}^{19} C.

## How do you calculate coulombs?

Charge in Coulombs = **Current in Amperes × Time in Seconds**

If a current of 30 A flows for 50 s, then the electrical charge in the circuit is 1500 C.

## How do you convert coulombs to charges?

How to Convert Electron Charge to Coulombs. To convert an electron charge measurement to a coulomb measurement, **divide the electric charge by the conversion ratio**. The electric charge in coulombs is equal to the electron charge divided by 6.2415E+18.
