Answer:
The mass of the titanium alloy is 7.005 g.
Step-by-step explanation:
Heat of fusion of titanium =
Amount of heat required to melt the titanium alloy of mass m:
Q = 2,960 Joules
m = 7.005 mg
The mass of titanium alloy is 7.01 g
calculation
Q=mHF
where
Q(heat)= 2960 j
M(mass) = ?
Hf( heat of fusion) = 422.5 j/g
make M the subject of the formula by diving both side of equation by Hf
M=Q/Hf
M= 2960 j/422.5 j/g = 7.01 g
