A student has two substances at a lab table. One substance is iron pyrite (fool's gold) and the other is real gold. After placin

g a 20.0-gram sample of iron pyrite into 40.0 mL of water in a graduated cylinder, it displaces 4.0 mL of water. The density of real gold is almost 4 times larger than iron pyrite. If a 20.0-gram sample of real gold is placed into the same amount of water, approximately how much water will be displaced?

Answer:The correct answer is option A.

Explanation

Mass of the iron pyrite= 20 grams

Volume water displaced by the iron pyrite = 4 mL

Density of iron pyrite=d_i=\frac{Mass}{Volume}=\frac{20 g}{4 mL}=5 g/mL

d_g=4\times d_i(Given)

d_g=4\times 5 g/mL=20 g/mL

Mass of gold = 20 g

Volume of water displaced by the 20 grams of water = V

D_g=20 g/mL=\frac{20 g}{V}

V = 1 mL

20 grams of gold will displace 1 ml of water.So, the correct answer is option A.

Based on what you know about matter explain why the food coloring mixes at different rates
emmasim [6.3K]

Answer:

Matter has different densities. Different food colorings have different densities. Those with a higher density will sink to the bottom and mix much easier than one with a lower density. The higher density also contains more particles making it easier to mix or give it a fuller color.
