Question

four moles of a compound x weigh 176 g. compound x is

Answer 1

Hii...

Moles = Given mass / Molar mass(M)

Given - : Moles = 4 and Given mass = 176 gram .

Now,

=> 4 = 176/M

=> M = 176/4

=> M = 44

So , the compound is Scandium .

Answer 2

Mass of the 4 moles of compound = 176 gm.

⇒ Molar mass of the compound = 176/4

= 44 g/mole.

∵ 44 g/mole is the molar mass of the gaseous compound called as Carbon Dioxide.

Hence, the Compound X is Carbon Dioxide.  

Its Chemical Formula is CO₂.  It is little acidic in nature.

It turns the moist blue litmus faint Red.

Hope it helps.
