Answers:

Kg of Ca in SN remnant = (20 x 2.0 x 1030 kg) x 0.000165
= 6.6 x 1027 kg of Ca in remnant
Glasses of milk = total Ca in remnant / Ca in 1 glass
= (6.6 x 1027 kg) / (300 mg x 1kg/106mg)
= 2.2 x 1031 glasses of milk!
Total Ca in remnant compared to mass of Earth = (6.6 x 1027 kg) / (6.0 x 1024 kg)
= 1,100 times mass of Earth
