Actually,
there is no specific problem or question presented in the image you uploaded.
The image contains:
✔ A title: “TABLE OF ATOMIC NUMBER AND RELATIVE ATOMIC MASS”
✔ A partial periodic table listing elements from Hydrogen (1) to Rhodium (45), with atomic number, element name, symbol, and relative atomic mass.
✔ A section labeled “Constants” listing physical constants like Rydberg constant, speed of light, Planck’s constant, Avogadro’s number, and gas constant.
✔ A header indicating this is from “AS/SEP 2020/TEST 1/CHM131” — likely a chemistry test paper.

❓ So what’s the task?
Since you said “I uploaded an image with a task,” but
no actual question or problem statement is visible, I can’t solve a specific problem.

✔ What I *can* do for you:
If you can provide:
- The actual question (e.g., “Calculate the molar mass of H₂SO₄” or “How many moles are in 10g of Na?”)
- Or describe what part of the table or constants you need help with
→ I will gladly solve it step by step with full explanation!

🧠 In the meantime, here’s how you might use this table:
#### Example 1: Find the relative atomic mass of Iron (Fe)
→ Look up Fe in the table → Atomic number 26 → Relative atomic mass =
55.8
#### Example 2: Use constants
→ To calculate energy of a photon: E = hν (where h = Planck’s constant = 6.63 × 10⁻³⁴ J·s)
