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.

The empirical formula is the formula that shows the ratio of the atoms in its simplest form, this is using the smallest whole numbers.
</span><span />
<span>The empirical formula may or may not be the same molecular formula.
</span><span />
<span>In this case you are given the molecular formula Hg₂(NO₃)₂. Since, the ratio of the atoms of Hg, N, and O is 2: 2: 6, respectively, the same ratio is expressed if you divide by the greatest common factor (GCF).
</span><span>
</span><span>
</span><span>The GCF of 2, 2, and 6 is 2. So, the ratios can be simplified to 1:1:3, meaning 1 mol of Hg, 1 mol of N, and 3 mol of O or HgNO₃.</span>
GPE is the gravitational Potential Energy which is given by mgh.
mg is the gravitational force(a force) and h is the height of the object(or distance of the object from earth's surface)
SO GPE = mg (force) x h (distance)
The type of energy used is kinetic energy. Kinetic energy is the energy of motion.
