Question

How many moles of sodium atoms correspond to 1.56x10²¹ atoms of sodium?

Answer 1

Explanation:

Given,

no. of atoms of sodium = 1.56 × 10^21;

1 mole of sodium = 6.022 × 10^23;

No. of mol corresponding to the given atom of sodium = (1.56 × 10^21)/(6.022 × 10^23);

= 0.259/100;

= 0.00259 mole.

That's all.
