1.	A piece of wax weight 18.80 g wt in air. A piece of metal is found to weight 17.03 g wt in water. It is tied to the wax and both together weight 15.23 g et, in water . Find the sp. Gravity of wax.
Answer» Solution :WEIGHT of wax in air = `18.80 g wt`. Weight of metal in water =`17.03 g wt`. Weight of (metal+wax) in water `= 15.23 g wt` Weight of wax in water = `15.23 - 17.03=-1.80 g wt`. Loss of weight of wax in water =`18.80 -(-1.80) = 20.60 g` wt. SP. GRAVITY of wax. =`("weight of wax in air")/("loss weight in water") = (18.80)/(20.6) = 0.91`.
