Need asap its due today these questions
1.what two sets of units can be used to describe density? why are they interchangeable?
2.a solid block with a length of 6.0 cm, a width of 3.0 cm, and a height of 3.0 cm has a mass of 146 g. what is the block’s density? show all work.
3.to determine the density of an irregularly shaped object, a student immersed the object in 21.2 ml of water in a graduated cylinder causing the level of the water to rise to 27.8 ml. if the object has a mass of 22.4 grams, what is the density of the object? show all work.
4.what is the difference between a measured value and an accepted value? how are these values used to determine the precision of your answer?
5.during a lab activity, students calculate the density of an element to be 7.78 g/cm3. the density listed on the periodic table is 7.13 g/cm3. calculate the percent error and identify the element.
