Molecular formula of aspartame = C14H18N2O5 Molecular mass of aspartame = ( 12 * 14 ) + ( 1 * 18 ) + ( 14 * 2 ) + ( 16 * 5 ) = 294 The number of moles = 10 / 294 = 0.034 mole

When heating water, it takes energy to heat the water molecules that can overcome the forces of attraction between them( hydrogen bond ) and thus the water molecules are separated from each other and turn into a gaseous state

CO_(g)    +  1/2  O_2(g)  ــــــــــــــــــــــــــــــــ>    CO_2(g)

Indicate that the outer shell of sodium atom contain only one electron .which removing easily ,so sodium atom charge in chemical reaction is Na⁺¹

Density  =  mass / volume Concentration = mass of solute /  molecular wieght * volume of solution if Concentration  Increase so the mass will be  Increase then the Density   will be  Increase .
