1.	Which of the following correctly represents 180 g of water ? 5 moles of water (ii) 10 moles of water (iii) `6.023xx10^23` molecules of water (iv) `6.023xx10^24` molecules of waterA. (i) and (ii)B. (i) and (iv)C. (ii) and (iv)D. (ii) and (iii)
Answer» 18g of `H_2O`=1 mol 180g of `H_2O` = 10 mol 18g of `H_2O=6.023xx10^23 " molecules of " H_2O` 180g of `H_2O = (6.023xx10^23)/(18)xx180` `=6.023xx10^24 " molecules of " H_2O`

Which of the following statements is correct about the reaction given below:- `4Fe(s)+3O_(2)(g)rarr2Fe_(2)O_(3)(g)`A. Total mass of iron and oxygen in reactants = total mass of iron and oxygen in product, therefore, it follows law of conservation of mass.B. Total mass of reactant = total mass of product, therefore, law of multiple proportions is followed.C. Amount of `Fe_2O_3` can be increased by taking any one of the reactants (iron or oxygen ) in axcess.D.
