I will give brainliest!!1.Calculate the density of aluminum if you have a piece of aluminum that has a volume of 48.9cm^3.When the prose is measured it is found to have a mass of 132g. 2.A small amount of copper is found to have a mass of 27g. Calculate the density of copper if the volume of the sample is 3.0cm^3(please show all steps)

2-bromo-2-methylbutane undergoes an e1 elimination reaction in the presence of ethanol. in the next reaction only one of the possible products is represented. although the product shown is not the major product of the reaction, notice that there is more than one way it can be produced. complete the mechanism and draw the missing substances.
