Question

Number of electrons in I7g of
OH​

Answer 1

Given,

Molar Mass of OH = (16+1) g

= 17 g

Given Mass = 17 g

No. of moles = (17/17) = 1

No. of molecules = 6.022*10²³ molecules

No. of electrons in 1 molecule = (8+1) = 9 electrons

No. of electrons in 6.022*10²³ molecules = (9*6.022)*10²³

= 54.198*10²³ electrons

or, 5.4198*10²⁴ electrons

I hope this helps.
