Write the following in scientific 8 notation: 8,642 x 10 A chemistry student mixes rubbing alcohol, water, and honey in a beaker. She noticed that the honey is at the bottom of the beaker, the water is in the middle and the rubbing alcohol is at the very top. Explain this observation in relation to the relative densities of rubbing alcohol, water, and honey. Write the following in scientific notation: 0.0000065 Write the following in ordinary notation: 1.57 x 106 Which unit is larger: meter, hectometer? What is the abbreviation of a decigram? Aluminum has a density of 2.669g/mL. Suppose a student measures the mass to be 14.3g. Calculate the volume of this piece of aluminum. Ryan measured a piece of aluminum to be 12.21g.
