Energy lost to condense = 803.4 kJ
<h3>Further explanation</h3>Condensation of steam through 2 stages:
1. phase change(steam to water)
2. cool down(100 to 0 C)
1. phase change(condensation)
Lv==latent heat of vaporization for water=2260 J/g
2. cool down
c=specific heat for water=4.18 J/g C
Total heat =
Answer:
56.44 %
Explanation:
The formula of copper(II) sulfate pentahydrate is .
In order to calculate the mass percentage of water in it, we may assume that we have 1 mol of copper(II) sulfate pentahydrate. In general, the mass percentage is a ratio between the mass of a component and the total mass of the compound expressed in percent:
Since we're taking 1 mole of a substance here, we may state that the mass percentage of water will be calculating using molar masses instead:
Notice that we take 5 molar masses of water, as 1 mole of copper(II) sulfate pentahydrate contains 5 moles of water molecules, then:
