The battery itself contains chemical energy, which is converted to electrical energy, and then converted to mechanical energy.
Hint: A mole is the entity that denotes 6.022×1023 particles.

Yes. Strong bases are too. In fact, they’re more dangerous to your skin than acids.
The molarity of a solution if it tale 12.0 grams of Ca(No3)2 is calculated as below
molarity = moles/volume in liters
moles = mass/molar mass = 12.0 g/ 164 g/mol = 0.073 moles
molarity is therefore = 0.073/0.105 = 0.7 M
