Given :
Mass of urea = 5.6 g
To find :
The number of moles and molecules of urea
Formulae :
i. Number of moles = \(\frac{Mass\,of\,a\,substance}{Molar\,mass\,of\,a\,substance}\)
ii. Number of molecules = Number of moles × Avogadro’s constant
Mass...
(B) mixture
The mixture show, the properties of its constituent substance while the compounds show different properties to its constituent (substance).
