What is the mass of a titanium alloy that has a heat of fusion of 422.5 joules/gram and requires 2,960 joules of energy to melt completely use the formula q = mhf

 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

The mass of the titanium alloy is 7.005 g.

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 the titanium alloy is 7.005 g.
