10000000 or $10^{7}$ grains of sand

Step-by-step explanation:

The mass of a grain of sand is about $10^{-3}$ gram.

Total weight of the sand in a bag is = 10 kg = 10000 gms

Let there are n grains of sand in the bag weighing 10 kg of sand.

So weight of n grains will be = number of grains × weight of one grain = 10000

$n.(10)^{-3}=10000$

$n=\frac{10000}{10^{-3}}=10000(10)^{3}$

n = 10000 × 1000 = 10000000

n = $10^{7}$

Therefore answer is $10^{7} Or 10000000$ grains of sand
