Ask AI: How many molecules of H2 will be Produced from 10.2g H2) in the following reaction

It looks like there’s a typo in your question: you wrote “10.2g H2)” — I assume you mean **hydrogen gas (H₂)**. You mentioned a reaction, but did not provide a balanced chemical equation. I'll proceed with a common example: the reaction of hydrogen with oxygen to produce water: **Balanced equation:** \[ 2H_2 + O_2 \rightarrow 2H_2O \] If your question is about **how many molecules are in 10.2g of H₂** (which are available for the reaction), here’s how to solve it: --- ### Step 1: Find the molar mass of H₂ - H₂: 2 × 1.008 g/mol = **2.016 g/mol** ### Step 2: Calculate moles of H₂ \[ \text{Moles of H}_2 = \frac{10.2\,g}{2.016\,g/mol} \approx 5.06\,mol \] ### Step 3: Convert moles to molecules \[ \text{No. of molecules} = 5.06\,mol \times 6.022 \times 10^{23}\,\text{molecules/mol} \] \[ \text{No. of molecules} \approx 3.05 \times 10^{24}\,\text{molecules of H}_2 \] --- **Final Answer:** **About \(3.05 \times 10^{24}\) molecules of H₂** will be produced (or present) from 10.2 g H₂. --- If you meant a different reaction or are asking how many H₂ molecules **are produced** as a product, please clarify the full chemical equation!
