**1. The problem statement, all variables and given/known data**

A 4.5 Volt is labeled: 4.5 V ; 1600 mAh (milliamperehour). This battery is the energy source of a chocolate lift. Find the number of kilograms of chocolater you can Transport with this lift up to the summit. The summit is 1000 meter above the valley Station.

**2. Relevant equations**

The solution is 2.6 kg

**3. The attempt at a solution**

I assume that my start is correct:

J = C * V

so

J = (1600 mAh / (3600 sec * 1000)) * 4.5 V

isn’t it?

Is the solution 0.002 J then? What did I wrong?

How do I have to go on?

Thanks in advance!
