Chapter 7: The Mole and Chemical Composition
... Notice that the unit of mole is abbreviated (mol), we like to abbreviate whenever possible in chemistry, even if it is only 1 letter… You can also use this same technique to convert from moles of an element or compound to grams of that element or compound. See…we use a balance to measure out grams ...

Magnets and Magnetic Fields
... • One way to increase the force is to increase the current in the wire, but large currents can be fire hazards. • A safer way to create a strong magnetic field that will provide a strong force is to wrap the wire into a coil. This creates a solenoid. – The coil of a solenoid allows the magnetic fiel ...
