if mole were define to be 2 into 10 power 24 instead of Avogadro's number what would be the mass of 1 mole of calcium atom

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 $6.022\times 10^{23}$ number of atoms.

As, $6.022\times 10^{23}$ number of atoms present in 40 grams of calcium atom

So, $2\times 10^{24}$ number of atoms present in $\frac{2\times 10^{24}}{6.022\times 10^{23}}\times 40=132.84$ 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 atom
because, one mole of a substance is equal to its atomic mass if the substance is atomic
therefore 1 mole of Ca atom= 40amu
