What is the proper way to report this calculation ?

17.34 / 3.45?

• 5.026 because the 17.34 has the most sigfigs

• 5.03 because the 3.45 has the fewest sigfigs

• 5.026087 because you need the most decimal places for accuracy

• 5 because you should round the final answer to the nearest whole number

A jade stone, is dropped into a graduated cylinder. It displaces the water in the cylinder from 50 milliliters (ml) to 65 ml. If the jade stone has a mass of 1 grams, what is its density of the stone in grams/cubic centimeter (g/cm3).

Hint (1ml = cm³)

• 0.066 g/cm³

• 6.6 g/cm³

• 66.6 g/cm³

• 666 g/cm³
