Question

calculate the mass of 9.099*10^23 no. of nitrogen atom​

Answer 1

Answer:

To find Mass of x no. of atoms, we need to find how many moles they constitute.

So, 6.022 * 10^23 atoms - In 1 mole

9.099 * 10 ^ 23 atoms - Will be there in 'x' moles

• x = Given atoms / Atoms in one mole
• x = 9.099 * 10 ^ 23 / 6.022 * 10^23
• x = 1.51 Moles

Mass of 1 mole of Nitrogen atom = 1 grams

Mass of x moles of Nitrogen atom = 1 * x Grams

Mass of 1.51 moles of Nitrogen atom

• = 1 * 1.51
• = 1.51 Grams ( Answer )
