A molecule has an empirical formula of ch, and its molar mass is known to be 26 g/mol and the  molecular formula is C₂H₂ ethyne

Molecular formula of compound is (CH)n and the given molar mass is 26g/mol

Molar mass of (CH)n, C=12=n(12+1)=13n

So 13n and n=2

=13×2=26 and given molar mass is also 26g/mol

So here two carbon and two hydrogen so molecular formula is C₂H₂ and name is ethyne

Know more about molecular formula

Can swords shatter from cold temperatures
sp2606 [1]
Depends on how the sword is made, what materials are used and temperature used but yes they can shatter.

When molecules cool down they stop vibrating and moving as much and so they "shrink" and the metal of the sword becomes brittle. sometimes they shrink at different phases which cause tension in the sword if this tension is strong enough it can cause the metallic bonds to break causing the sword to shatter.

hope that helps
