MASS, VOLUME, AND DENSITY. MASS. MASS IS THE AMOUNT OF MATTER IN AN OBJECT. IT IS MEASURED IN GRAMS. VOLUME. VOLUME IS HOW MUCH SPACE SOMETHING TAKES UP OR HOW BIG IT IS. LIQUIDS ARE MEASURED IN LITERS. VOLUME. SOLIDS HAVE VOLUME TOO. THEIR VOLUME IS MEASURED IN cm 3 .

MASS • MASS IS THE AMOUNT OF MATTER IN AN OBJECT. • IT IS MEASURED IN GRAMS.
VOLUME • VOLUME IS HOW MUCH SPACE SOMETHING TAKES UP OR HOW BIG IT IS. • LIQUIDS ARE MEASURED IN LITERS.
VOLUME • SOLIDS HAVE VOLUME TOO. • THEIR VOLUME IS MEASURED IN cm3. • SOME SOLIDS ARE REGULAR WHICH MEANS THEY ARE MADE ENTIRELY OF RIGHT ANGLES.
VOLUME • IRREGULAR OBJECTS HAVE SOME NON-RIGHT ANGLES. • ALMOST EVERYTHING!
VOLUME • 1 mL = 1 cm3 Sooo… 10 mL = ___ cm3 42 mL = ___ cm3 5234 mL = ___ cm3 8432542856758609121349543 mL = ___ cm3
DENSITY • DENSITY IS A COMBINATION OF MASS AND VOLUME. • IT IS THE AMOUNT OF MASS IN A GIVEN SPACE. • TO CALCULATE A DENSITY, DIVIDE SOMETHING’S MASS BY ITS VOLUME.
DENSITY • THE UNITS FOR DENSITY ARE g/mL FOR LIQUIDS AND g/cm3 FOR SOLIDS. • D=m/V
