Concepts:
The buoyant force
Reasoning:
When an object floats, the magnitude of the buoyant force is equal to the magnitude of its weight.
Details of the calculation:
The magnitude of the buoyant force is equal to the the magnitude of the weight wliquid of the displaced liquid.
wliquid = ρliquidVg.
The volume V of the displaced liquid is the volume of one half sphere,
V = 2πr3/3 = 2π(6cm)3/3 = 452cm3.
The magnitude of the weight of the object is wobject = mfrogg. (We are neglecting the weight of the air-filled pod.)
ρliquidVg = mfrogg.
mfrog = 1.35(g/cm3)452cm3 = 610g.
