Expert Answer
Dear student,
 
Density = mass/ volume
 
w1 = 70g, w2 = 60g, w3 = 55g
 
1 = 60/volume, volume = 60units ( in tap water)
 
density of air at sea level = 1/800 th density of water, density of tap water is approximately equal to 1.
 
1/800 = 70/volume = 56000 units ( in air)
 
PLease get back to us for further clarifications.
Thankyou
