Density is a physical property of a molecule that’s measured as mass per unit volume. (a) Given that density is usually expressed in the units of g/cm3, calculate the density of a cube of plastic that has a mass of 2.331 g and an edge length of 1.500 cm (volume of a cube is V = l3). (b) Draw two liquids in a graduated cylinder on a separate sheet of paper. You won’t submit the drawing as part of your answer. Liquid A has a density of 1.004 g/cm3 and Liquid B has a density of 0.6223 g/cm3. Assume they don’t mix. Label which liquid is on top and which liquid is on bottom, and then draw the cube where you would expect it to be if it’s dropped into the graduated cylinder with these two liquids. Explain the location for liquid A, liquid B, and the cube in the graduated cylinder.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

answer: they produce more slow than unicellular organisms.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
