<h3>
Explanation:</h3>
<u>Step 1: Define</u>
[RxN - Balanced] 2NaOH (s) + CO₂ (g) → Na₂CO₃ (s) + H₂O (l)
[Given] 1.85 mol NaOH
<u>Step 2: Identify Conversions</u>
[RxN] 2 mol NaOH → 1 mol H₂O
Molar Mass of H - 1.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol
<u>Step 3: Stoichiometry</u>
- Set up:

- Multiply/Divide:

<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 3 sig figs.</em>
16.6685 g H₂O ≈ 16.7 g H₂O

To estimate the number of ladybugs in the entire garden, Ajoy needs the dimension of the garden.
<h3>What is a dimension?</h3>
Dimensions in mathematics are the measure of the size or distance of an object or region or space in one direction.
Dimensional measurement is of fundamental importance for interchangeability and global trade.
Hence, to estimate the number of ladybugs in the entire garden, Ajoy needs the dimension of the garden.
