We are given that the specific heat of water is 4.18 J / g
°C. We know that the molar mass of water is 18.02 g/mol, therefore the molar
heat capacity is:
molar heat capacity = (4.18 J / g °C) * 18.02 g / mol
<span>molar heat capacity = 75.32 J / mol °C</span>

Answer:The number of atoms in 2.0 mole Al is A. 2.0 Al atoms. B. 3.0 x 1023 Al atoms.
Secondly, is aluminum an atom or molecule? Aluminum is the second element in the thirteenth column of the periodic table. It is classified as a post-transition metal and a "poor metal". Aluminum atoms contain 13 electrons and 13 protons. There are 3 valence electrons in the outer shell.
Answer: 18.97 L
Explanation:
This can be solved by the Ideal Gas equation:
Where:
is the pressure of the gas
is the volume of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas in Kelvin
Finding :
Therefore:
The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is <u>18.97</u> liters
