What quantity of heat would be evolved if 1.00g of sodium vapor condensed at its normal boiling point?
0.043*97000
To determine the quantity of heat evolved when 1.00g of sodium vapor condenses at its normal boiling point, we need to use the concept of heat of condensation. The heat of condensation (ΔHcond) is the energy released or absorbed when 1 mole of a substance changes from a gas to a liquid at a particular temperature.
In this case, we need to determine the heat of condensation for sodium. Let's break down the steps on how to find this information:
1. Search for reliable sources: Look for trustworthy scientific databases, textbooks, or online resources that provide information about the heat of condensation (ΔHcond) for sodium.
2. Calculate the molar mass of sodium: The molar mass of sodium (Na) is 22.99 g/mol.
3. Convert grams to moles: Divide the given mass of sodium vapor (1.00g) by the molar mass (22.99 g/mol) to find the number of moles.
Number of moles = Mass (g) / Molar mass (g/mol)
4. Multiply moles by heat of condensation: Multiply the number of moles of sodium by the heat of condensation obtained from the reliable source. This will give you the quantity of heat evolved.
Quantity of heat evolved = Number of moles × ΔHcond
Please note that the exact value of the heat of condensation for sodium may vary depending on the source you find. Make sure to use reliable data for accurate results.
