Question

The mass of 1.5055×10^23 CO molecules is
1) 4 avagadro no. U 2)7 avagadro no. U
3) 8 avagadro no. U 4)12 avagadro no. U

Answer 1

No. of molecules of the CO = 1.5055 × 10²³

∴ No. of molecules = mass/molar mass × Na.

⇒ mass = 1.5055 × 10²³/Na × 28

⇒ mass = 7 g.

Means 7 Avogadro's number.

Answer ⇒ Option (b).

Hope it helps.
