How many atoms are in 159 g of calcium?

159 g =

2.30 x 10 to the 24 power atoms cal

Sorry if this is confusing

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
