What mass of chlorine gas will react with 92.0 g of sodium?
Aleonysh [2.5K]
The balanced chemical reaction is:

2Na + Cl2 = 2NaCl

We are given the amount of sodium to be used for the reaction. This will be the starting point of our calculations.

92.0 g Na ( 1 mol Na / 22.99 g Na ) ( 1 mol Cl2 / 2 mol Na ) ( 70.9 g Cl2 / 1 mol Cl2) = 141.86 g Cl2

During the analysis, 0.00905 mol H2O is formed. Calculate the amount (mol) H in 0.00905 mol H2O.
sergeinik [125]

Answer:

0.0181 mol H

Explanation:

Step 1: Given data

Moles of water (H₂O) formed during the analysis: 0.00905 mol H₂O

Step 2: Calculate the amount (mol) H in 0.00905 mol H₂O

According to the chemical formula of water, the molar ratio of water to hydrogen is 1:2, that is, there are 2 moles of H per 1 mole of H₂O. We will use this conversion factor to calculate the moles of H in 0.00905 moles of H₂O.

0.00905 mol H₂O × (2 mol H/1 mol H₂O) = 0.0181 mol H
