Answer to Question #80480 in Physics for samantha

Question

1. What volume of water has the same mass as 100 mm3 of gold? What is the specific weight of gold?

Answer 1

The density of gold is
ρ_gold=19.3 ρ_water.
m_gold=m_water
ρ_gold V_gold=ρ_water V_water
V_water=(ρ_gold V_gold)/ρ_water
The volume of water:
V_water=19.3(100)=1930 mm^3=1.93 cm^3.
The specific weight of gold:
g_gold=ρ_gold/ρ_water =19.3
