Question

ice has density relative to the sea
water of 0.90, the portion of an Iceberg is submerged is

Answer 1

0.10 iceberg is submerged...
hope this helps u

Answer 2

V'/V=d'/d.

where:V→ Total Volume of ice
V'→ Volume of ice not submerged
d → density of ice
d' → density of liquid

d'/d = 0.9 (relative density)

Therefore

V'= 0.9V

that is volume of ice submerged 1/10 of original volume
