A 2.1880 g sample of a hydrate of Cu(NO3)2 was heated to drive off all of the water of hydration. The remaining solid weighed 1.6986 g. If Cu(NO3)2 X H₂O represents the formula of the hydrate, then what is the value of x? Note: The notation Cu(NO3)2 X H₂O indicates that there are x moles of H₂O for every mole of Cu(NO3)2 in the solid hydrate. Molar masses (in g mol¯¹): H, 1.008 Mg, 24.31 Ni, 58.69 N, 14.01 S, 32.07 Cu, 63.55 O, 16.00 Mn, 54.94 Hg, 200.6
