20.91 grams of ice can be melted

Further explanation

Q fusion = m x L

L = latent heat , kj/kg

m = mass, kg

Q = heat, kJ

Reaction :

H₂O(s)⇒H₂O(l)

Q = 6982.6 J=6.9826 kJ

L for ice = 3.34 x 10⁵ J/kg=334 kJ/kg

mass of ice :

[tex]\tt m=\dfrac{Q}{L}\\\\m=\dfrac{6.9826}{334}=0.020905~kg= 20.91~g[/tex]
