Specific Gravity
A 6.7 kg block of some unknown material is suspended from a spring scale and submerged in water. The spring scale reads 50.0 N.
What is the specific gravity of the block?
4.18
What is the density of the block?
4.18×103 kg/m^3
What is the specific gravity of the block?
4.18
What is the density of the block?
4.18×103 kg/m^3

How do you go about starting this problem?
NEW
Part 1. (mg)/(mg-(scale reading)) -no units
Part 2. For density, take your answer from part a and
multiply by 1000 . answer is in kg/m^3

Thats not working for me?
Im doing 7.7kg= 7700000mg/(7700000mg-58.6N)
and its giving me 1.00000761, so i put in 1.00 and its
wrong... any ideas please?

mg
its mass times gravity not milligrams
