is the ratio of mass to volume or mass divided by volume ratio of dirived form the equaltity between two different units that can be used to convert from one unit to the other mathmatical technique that allows you to use units to solve problems invovling measurments refers to the closeness of measurments to the correct or acceptd value of the quantity measured refers to the closeness of a set of measurements of the same quantity made int he same way caculated by the subtracting the accepted value from the experimental value consisting of all the digits known with certianty plus one final digit to each other if dividing one by the other gives the contant value to each other if the product is constant where the M factor is a number greater than or equal to 1 but less than 10  

1. Density
