the latent heat of fusion of mercury is 11.8 j/g. the amount of energy, rounded to the nearest tenth, needed to change 8.00 grams of mercury to a liquid is j.

the latent heat of fusion of mercury is 11.8 j/g. the amount of energy, rounded to the nearest tenth, needed to change 8.00 grams of mercury to a liquid is j.

Answer

Explanation:

Step1: Identify the formula

The formula for heat energy $Q$ during a phase - change is $Q = mL$, where $m$ is the mass and $L$ is the latent heat.

Step2: Substitute the given values

We are given that $m = 8.00\ g$ and $L=11.8\ J/g$. So, $Q=(8.00\ g)\times(11.8\ J/g)$.

Step3: Calculate the result

$Q = 8.00\times11.8=94.4\ J$.

Answer:

94.4
