Answer : The mass of 1 mole of calcium atom will be, 132.84 grams
Solution : Given,
Mass of calcium atom = 40 g
As we know that,
1 mole weighs 40 grams of calcium atom which contains number of atoms.
As, number of atoms present in 40 grams of calcium atom
So, number of atoms present in grams of calcium atom
Therefore, the mass of 1 mole of calcium atom will be, 132.84 grams
Verified answer
If 1 mole is equal to 2*10^24 , there will be no change in the mass of any atombecause, one mole of a substance is equal to its atomic mass if the substance is atomic
therefore 1 mole of Ca atom= 40amu
