magnitude of buoyancy force

If you soak a metallic ball which has a mass of $3$ kg and volume of $1000$ cc in special liquid, and the density of the liquid is $1.5 \times 10^3$ kg/ $m^3$ , then what is the magnitude of buoyancy force exerted by the liquid to the metallic ball? (Gravitational acceleration is $10$ m/ $s^2$ .)
