a) Would 1 gram of gold weigh more than 1 gram of aluminum? No. They are both one gram, so weigh the same. 1g gold would be more dense, but not weigh more. How would the volumes of these samples compare? The allinum has much more volume than the gold, because it is much less dense. b) If you had a 1 gram sample and a 10 gram sample of the same substance, how would you expect their volumes to compare? 1 gram would have much less volume than 10 grams. c) If you had 1 kg of silver, how much space would it take up? d) How many 100 g bars of copper would you need to fill a 1 L box? 1g=1/1000L 100g= 100/1000L = 10/100L = 0.1L So if 100g = 0.1L, and if 1L=1000g, then you would need to multiply both sides by 10, to make 1000g=1L, which means that you need 10 100g bars of copper to fill a 1L box.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

![Part 2: Problem Solving
Using what you have learned about density so far, answer the following questions. Be sure to show all calculations,
taking into account significant digits. Explain your reasoning thoroughly using complete sentences.
1. Use the table of density values below to answer the following questions.

c)
If you had 1 kg of silver, how much space would it take up?
d)
How many 100 g bars of copper would you need to fill a 1 L box? 1g= 1/1000L
100g= 100/1000L = 10/100L = 0.1L
aluminum
2.7
a) Would 1 gram of gold weigh more than 1 gram of aluminum? No. They are both one gram, so weigh the
same. 1g gold would be more dense, but not weigh more. How would the volumes of these samples
compare? The allinum has much more volume than the gold, because it is much less dense.
b) If you had a 1 gram sample and a 10 gram sample of the same substance, how would you expect their
volumes to compare? 1 gram would have much less volume than 10 grams.
So if 100g =0.1L, and if 1L=1000g, then you would need to multiply both sides by 10, to make
1000g=1L, which means that you need 10 100g bars of copper to fill a 1L box.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fddf4e71a-b7c5-4f9c-a910-6cdf990ad8cb%2F5ad98620-92e4-481b-988e-1ed00a1187bd%2Fubi41nc_processed.png&w=3840&q=75)

C, c is the only substance that is less dense than water, so it is the only substance that will float in
water.
50.5
b) If you had 1 kg of each substance, which one would take up the most volume? Explain.
If I had 1kg of each, substance A takes up the most. This is because it is the most dense.
c) If you had 1 L of each substance, which one would have the most mass? Explain.
The same, A takes up the most, because it is the most dense.

3. A small elevator with a volume of 100 L has a maximum weight capacity of 500 kg. If you had a 500 kg sample
of each of the following rare and precious substances, which one(s) could you fit in the elevator? Explain using
calculations and words.
D: 1.37 kg/L 1.37x500=685kg 1Lx500=500L 685kg/500L. Nope, D can't fit.
