zinc react with chlorine to form zinc chloride
Zn + cl2 ---> ZnCl2
calculate the number of moles of Zn
that is mass/molar mass of Zn(65.38g/mol)
moles= 4g/65.38 g/mol= 0.021moles
the reacting ratio of zinc to ZnCl2 is 1:1 from the reaction above
therefore the moles of Zncl2 is also 0.021 moles
mass= number of moles x molar mass
The molar mass of ZNCl2 = 65.38 + (35.2 x2) = 136.38 g/mol
Therefore the mass of Zncl2 = 0. 021 moles x 136.38 g/mol=2.86 grams

Zn is a metal that used several industries and factories for making a regular-use item. Zinc has also been beneficially used in the ecosystem and also helps to make the soil fertile. Zinc is take-up by the plant from soil to increase the shoot growth of the plant.
According to the law of mas of conversation, the mass of the element remains the same before the reaction and after the reaction.
The consumed mass and the produced mass are always the same in the reaction process.
Hence, the amount of zinc has remained the same in the reaction that is 1.4g.
