The Molarity of a solution = number of moles / volume.
Volume = 244ml = 0.244L
So it follows that number of moles = Molarity * volume
Number of moles = 0.135 * 0.244 = 0.03945.
Hence the number of moles = 0.03945
The correct answer is, tobacco.
Answer:
In Charles law, temperature and volume of the gas are kept at constant pressure. Where as in Boyle's law, pressure and volume of the gas are kept at a constant temperature. In Boyle's law, pressure and volume vary inversely where as, in Charles law, pressure and volume vary directly.
The final temperature of the mass of gold is 737 °C.
<h3>What is the specific heat capacity of gold?</h3>
The specific heat capacity of gold is 0.126 J/g/K
The final temperature, T2 of the gold is calculated as follows:
T2 = T + Q/mc
where;
T is initial temperature, m is mass, and c is specific heat capacity of gold.
T2 = 27 + 2.3 x 1000/(25 x 0.126)
T2 = 737 °C
Therefore, the mass and heat capacity of gold determines its final temperature.
