### Stoichiometry Problem: Calculating Grams of Water**Chemical Equation:**\[ 3 \text{Cu} + 8 \text{HNO}_3 \rightarrow 3 \text{Cu(NO}_3\text{)}_2 + 2 \text{NO} + 4 \text{H}_2\text{O} \]**Problem:**In the above equation, how many grams of water can be made when 18.5 moles of \( \text{HNO}_3 \) are consumed?**Instructions:**Round your answer to the nearest tenth. If your answer is a whole number like 4, report the answer as 4.0.**Molar Masses:**Use the following molar masses. If you do not use these masses, the computer will mark your answer incorrect.| Element | Molar Mass ||-----------|-------------|| Hydrogen | 1 || Nitrogen | 14 || Copper | 63.5 || Oxygen | 16 |### Process:1. **Identify the Mole Ratio:** \[ 8 \text{ moles of HNO}_3 \rightarrow 4 \text{ moles of H}_2\text{O} \] Therefore, \[ 18.5 \text{ moles of HNO}_3 \rightarrow \left(18.5 \div 8\right) \times 4 \text{ moles of H}_2\text{O} \]2. **Calculate Moles of Water:** \[ \text{Moles of H}_2\text{O} = \left(\frac{18.5}{8}\right) \times 4 \] \[ \text{Moles of H}_2\text{O} = 2.3125 \times 4 \] \[ \text{Moles of H}_2\text{O} = 9.25 \]3. **Calculate Grams of Water:** The molar mass of water (\( \text{H}_2\text{O} \)): \[ (2 \times 1) + 16 = 18 \text{ g/mol} \] Total grams of water: \[ 9.25 \text
