Question

calculate the mass of 10^25 molecules of CaCO₃
{Plzz Urgent}

Answer 1

We know that the molecular mass of CaCO3 is 100g/mole

Therefore, 1 Mole =100g

Since 1 Mole is 6.022 x 10^23 molecules.

Therefore no. of moles of 10^25 particles is 0.166 x 10^2 OR 16.6 moles.

Hence, mass of 10^25 molecules is,

16.6 x 100, i.e 1660 grams.

OR 1.660 KG
