Abattery weighing 0.525 lb can store 30.8 kcal of electrical energy. what is the energy density of the battery in wh per kg? give your answer to an accuracy of 3 significant figures.

Energy Density: 129.412

Explanation:

First of all, let's convert the battery weighing from pounds to kilograms:

0.525 lb x = 0.238 kg

Now let's convert the electrical energy from kcal to Wh:

30.8 kcal x = 30.8 Wh

Now we can calculate energy density as follows:

Energy Density =

Energy Density = 129.412

answer:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.
