Answer : The number of atoms present in 159 g of calcium are
Explanation :
First we have to calculate the moles of calcium.
Molar mass of calcium = 40 g/mole
Now we have to calculate the number of atoms of calcium.
As, 1 mole of calcium contains number of atoms of calcium
So, 3.975 mole of calcium contains number of atoms of calcium
Therefore, the number of atoms present in 159 g of calcium are
