Question

3.3 determining specific gravity cereal and get the most cereal for your money. You have A. Imagine that you want to buy a box of breakfast search to two brands of cereal that are sold in boxes of the exact same size and price. The boxes are made ofo and have no labeling of weight. Without opening them, how can you tell which box contains the most cereal? B. Like the cereal boxes above, equal-sized samples of different minerals often have different weights. If you hold a mineral sample in one hand and an equal-sized sample of a different mineral in the other hand, then it is possible to act like a human balance and detect that one may be heavier than the other. This is called hefting, and it is used to estimate the relative densities of two objects. Heft the three mineral samples provided to you, then write sample numbers/letters on the lines below to indicate the sample densities from least dense to most dense. (Most dense) C. In more exact terms, density is a measure of an object's mass (weighed in grams, g) divideby is voume upnccete, m?.Densit Scientists use the Greek character rho () to represent density, which is always expressed in g/cm. What is the density of a box of cereal that is 20 cm by 25 cm by 5 cm and weighs 0.453 kg? Show your work 9-

Explanation / Answer

A. Specific gravity = density of cereal/ density of water Density of water = 1 Specific gravity = density of cereal = mass of cereal/ volume of box Specific gravity of brand 1 = mass of cereal of brand 1 / volume of box Specific gravity of brand 2 = mass of cereal of brand 2 / volume of box Since volume of box is same, by comparing the specific gravity of cereals, mass of the brand can be calculated and the brand with more cereals can be found.
