D. 15,020 J

heat = 45 x 333.7 j = 15016.5j

Answer:

d. 15,020 J

Explanation:

As we know that heat required to change the phase of of ice is given as

[tex]Q = mL[/tex]

here we we know that

m = 45.00 gm

also we know that

Latent heat is L = 333.7 J/g

Now from above formula

[tex]Q = 45 \times 333.7[/tex]

[tex]Q = 15020 J[/tex]

so correct answer will be

d. 15,020 J
