## What is the mass of 2 moles of sodium?

Hence, the number of grams of sodium is present in 2 moles is **46g** .

## How many grams are in 5 moles of sodium?

Hence, 5 moles of sodium carbonate weigh **530 grams**.

## How many moles of electrons weigh 1kg?

Or, 1 kg will contain = $dfrac{1}{{9.108 times 6.022}} times {**10^8}$ moles** of electrons. Thus, $dfrac{1}{{9.108 times 6.022}} times {10^8}$ moles of electrons will weigh one kilogram. So, the correct answer is “Option D”.

## How do you calculate 1 mole of sodium?

## How do you calculate moles of sodium?

One mole of sodium (Na) is **22.99 g**, and 1 mole of chlorine is 35.45 g. For sodium chloride (NaCl) they are in a ratio of 1:1 so the molar mass of NaCl is 22.99 + 35.45 = 58.44 g/mol.
