Question

Hey Friends...I Want The answer In The Upper Image By Solving It​

Answer 1

$\mathcal\green{ᴀɴsᴡᴇʀ}$

ᴍᴏʟᴇ = $\frac{ɢɪᴠᴇɴ\:ᴍᴀss }{ᴍᴏʟᴇᴄᴜʟᴀʀ\:ᴍᴀss}$

ɢɪᴠᴇɴ ʀᴀᴛɪᴏ ɪs 14 : 3

ɴ = 14x

ʜ = 3x

ᴛʜᴇɴ ,

ᴍᴀss ᴏғ $ɴʜ_3$ = 17x

ʟᴇᴛ ɢɪᴠᴇɴ ᴍᴀss ʙᴇ 34x

ᴍᴏʟᴇ = $\frac{34x }{17x}$

ᴍᴏʟᴇ = 2

ʜᴇɴᴄᴇ 2 ᴍᴏʟ. ɪs ᴘʀᴇsᴇɴᴛ ɪɴ $ɴʜ_3$
