Alicia's cheapskate boyfriend gave her a ring he claims is 24 carat gold. Alicia is skeptical. After chem class the next day she measures the mass of the ring, finds the volume of the ring by water displacement, and then calculates the density of the ring. should she treasure the ring as his first truly generous gift to her, or throw it at him the next time he walks by?
Mass: 15.28g
Final Volume: 43.7mL
Volume of ring: ??
Density: ??
My identical wksht states that the initial volume is 42.2 mL. This means that the volume is 1.5 mL, and the density is 10.19 g/mL, but I don't see how it relates to the 24 carats..
You need the initial volume to find the volume by displacement of water.
Well, Alicia's cheapskate boyfriend might be in for a surprise! Let's crunch the numbers here.
To find the volume of the ring, Alicia measured its mass and found the volume by water displacement. However, you forgot to provide the volume of the ring, so I can't really help with that. But don't worry, I'll make sure to keep this suspenseful, just like any good mystery novel!
Now, let's move on to the density. Density is calculated by dividing the mass of an object by its volume. Since we don't have the volume, we can't calculate the density either. Oh, the plot thickens! This is turning into a real nail-biter, isn't it?
Anyway, without the volume and density, it's hard to determine if the ring is truly made of 24 carat gold or just fool's gold. So, my dear Alicia, it seems like you'll have to keep wondering whether to treasure the ring or throw it at your cheapskate boyfriend the next time he walks by. Who knows? Maybe it's a test to see how much you value material things. Or perhaps he's just trying to lighten your hand jewelry collection. The mystery remains unsolved!
Remember, though, in matters of the heart, the value of a gift is about the thought and sentiment behind it, not just the material worth. So, take this situation with a pinch of humor and decide what matters to you most.
To help Alicia determine if the ring is indeed made of 24 carat gold, she needs to calculate the density of the ring. The density of an object can be obtained by dividing its mass by its volume.
Alicia has already measured the mass of the ring, which is 15.28 grams. Now she needs to find the volume of the ring.
To do that, Alicia measures the volume of the ring by water displacement. Here's how she can do that:
1. Fill a graduated cylinder partially with water. Note the initial volume of the water.
2. Carefully lower the ring into the graduated cylinder, making sure it is fully submerged but not touching the sides.
3. The water level in the graduated cylinder will rise due to the displacement caused by the ring. Take note of the final volume of the water.
4. Subtract the initial volume of the water from the final volume to calculate the volume of the ring.
Once Alicia determines the volume of the ring, she can proceed to calculate its density using the formula:
Density = Mass / Volume
Now, let's plug in the given values:
Mass = 15.28 grams
Volume = ?? (determined through water displacement)
Density = 15.28 g / Volume
By calculating the density, Alicia can compare it to the known density of 24 carat gold, which is approximately 19.32 grams per milliliter. If the calculated density matches, or is close to, the known density of 24 carat gold, Alicia could conclude that the ring is indeed made of gold. If not, she may have reason to doubt the authenticity of the ring.
By going through these steps, Alicia can make an informed decision about whether to treasure the ring or confront her boyfriend about its authenticity.
