Suppose you are measuring the mass of a solid sample on a balance using a weigh boat. You record the data in a table.Mass of weigh boat: 2.147 g

Mass of weigh boat and sample: 6.096 g

What is the mass of the solid sample (in g)?

To find the mass of the solid sample, you can subtract the mass of the weigh boat from the combined mass of the weigh boat and sample. The formula is:

\[
\text{Mass of solid sample} = \text{Mass of weigh boat and sample} - \text{Mass of weigh boat}
\]

Given:
- Mass of weigh boat and sample = 6.096 g
- Mass of weigh boat = 2.147 g

Now, calculate the mass of the solid sample:

\[
\text{Mass of solid sample} = 6.096 \, \text{g} - 2.147 \, \text{g}
\]

Let's calculate that.The mass of the solid sample is **3.949 g**.

Would you like more details or have any questions? Here are five related questions you might find interesting:

1. How would rounding affect this value if fewer significant figures were used?
2. What if you needed to measure the sample mass in milligrams instead of grams?
3. How would you calculate the density of the sample if its volume is known?
4. What would happen if the balance had a measurement uncertainty of ±0.001 g?
5. How would you find the total mass if you added another sample with a mass of 4.523 g?

**Tip:** When performing subtraction in measurements, ensure that your result has the same number of decimal places as the measurement with the fewest decimal places.
