It looks like you've uploaded an image containing a set of physics or chemistry problems related to
density, mass, volume, and unit conversions. Since I can't view images directly, I’ll need you to
describe the content of the image or
type out the problems so I can help solve them.
However, based on your message and the text fragments you've included (like "1.61g/cm³", "0.87g/cm³", etc.), it seems like the problems involve:
- Calculating density using the formula:
\[
\text{Density} = \frac{\text{Mass}}{\text{Volume}}
\]
- Converting units (e.g., grams to kilograms, cm³ to m³).
- Finding mass or volume when two of the three variables (mass, volume, density) are known.
- Possibly interpreting data from a diagram (like a block or cylinder).
Example Problem (based on your text):
Let’s assume one of the problems is:
> A metal block has a mass of 2.7 g and a volume of 1 cm³. What is its density?
Solution:
\[
\text{Density} = \frac{2.7\,\text{g}}{1\,\text{cm}^3} = 2.7\,\text{g/cm}^3
\]
Or another:
> A substance has a density of 1.3 g/cm³ and a volume of 100 cm³. What is its mass?
\[
\text{Mass} = \text{Density} \times \text{Volume} = 1.3\,\text{g/cm}^3 \times 100\,\text{cm}^3 = 130\,\text{g}
\]

Please
type out the full problem(s) from the image, or describe them in detail (including any diagrams or values), and I’ll walk you through each step with clear explanations.
Alternatively, if you can paste the text from the image here, I’ll solve it for you right away.
Parent Tip: Review the logic above to help your child master the concept of density calculations worksheet answers.
