1.	d) The density of aluminium is 2-7 g cmsand that of brass 8-4 g em. The correct(i) Equal masses of aluminium and brass(ii)/ The mass of a certain volume of brassstatement is:have equal volumesis more than the mass of equal volumeof aluminium(iii) The volume of a certain mass of brassis more than the volume of equal massof aluminium(iv) Equal volumes of aluminium and brasshave equal masses.
Answer» Given density of aluminum is 2.7 g/cm³ and that of brass is 8.4 g/cm³. so density of brass > density of aluminum so , higher the density, higher will be the mass of a certain volume as M = D.V , keeping V constant.. mass will be greater if D is greater so, option B is correct.

Answer»

Given density of aluminum is 2.7 g/cm³ and that of brass is 8.4 g/cm³.

so density of brass > density of aluminum

so , higher the density, higher will be the mass of a certain volume as M = D.V , keeping V constant.. mass will be greater if D is greater

so, option B is correct.
