Question

help me with the density sheet

Answer 1

1) Mass and Volume

2) gram/cc and Kg/m^3

3) 1 gm/cc

4) Mass of water= Volume*density
=55*1= 55 grams

5)(a)
Volume of A= 500/5= 100cm^3
Volume of B= 650/6.5= 100cm^3

Since, Both the objects have densities more than water and equal volume, so will sink to the bottom and displace equal liquids.

(b) No, the two cannot be made of same substance as they have different densities.


6) Density of Silver= Mass of Silver piece/Volume of silver piece
Volume of silver piece= 31.5/10.5
= 3 cm^3


7)Mass of sample = 10cc*7.9g/cc
= 79 grams


8) Density of Iron= Mass of Iron sheet /Volume of Iron sheet
7.9g/cc= 50000g/(L*120cm*2cm)
Length of Iron sheet = 26.3 Cm
