How was urea originally produced in the lab according to the text?

One sugar cube (sucrose) was added to a 100ml beaker. Enough concentrated H2SO4 (HIGHLY ACIDIC) was added to soak the cube completely (about 2 mL). The mixture was allowed to set for several minutes. One of the products of the reaction was a gas which he was able to detect by condensing it on the surface of a cool watch glass set on top of the beaker. The liquid was tested with cobalt chloride paper and was determined to be H2O. Also, a solid residue product of the reaction resembled charred wood or carbon. The reaction beca

. . .became hot (indicating an exothermic reaction).

dont take my guess serious but
H2SO4 +sucrose - heat release-> h20 + urea

You work out the coefficients

first convert

H2SO4 and sucrose  from from ml to mols
