The mass of steam required to raise the temperature of water is 3.5 g.
The given parameters;
- <em>mass of the benzene, = 47.6</em>
- <em>initial temperature of the benzene, = 5.5 ⁰C</em>
- <em>final temperature of the benzene = 30 ⁰C</em>
The molar mass of Benzene = 78.11 g/mol
The molar mass of water = 18 g/mol
The number of moles of the Benzene is calculated as follows;
The mass of steam required is calculated as follows;
<em>heat lost by steam = heat absorbed by benzene</em>
<em />
Thus, the mass of steam required to raise the temperature of water is 3.5 g.
