Question

11. A piece of iron weighs 155 gf in air and 133 gf in water. What is its volume and the relative density of the iron? What would be the same piece of iron appear to weigh in alcohol of density 0.8 gcm?​

Answer 1

Answer:

volume is 22

density is 7.04

Answer 2

Explanation:

1) Volume

= As we know,

loss in weight of body = true weight - apparent weight

= 155 - 133

= 22cc

2) Density of iron

$density \: = \frac{mass}{volume} \\ \\ = \frac{155}{22} </p><p>$

= 7.05 (approx)

3) weight of iron in alcohol

= 137.4
