<h3>Mass of aluminium : 13323.47 g</h3><h3>Further explanation</h3>
Given
Lf=latent heat of fusion of Al = 95 cal/g
Q = 1,265,730 cal
Required
mass of Aluminium
Solution
The heat to change the phase can be formulated :
Q = m.Lf (melting/freezing)
Input the value
1,265,730 cal = m . 95 cal/g
m = 1,265,730 cal : 95 cal/g
m = 13323.47 g
I prefer using the slope formula because it’s easy to pick two numbers on a graph and solve for the slope with a simple equation.
