The mathematical expression for heat capacity at constant pressure is given as:
(1)
where, Q = heat capacity
= molar heat capacity at constant pressure
= change in temperature
n = number of moles
Therefore, = 
= 
Number of moles =
= 
= 0.186 mole
Put the values in formula (1)
(conversion of degree Celsius into kelvin)
= 
= 6.32 J /mol K
Hence, molar heat capacity of benzene at constant pressure = 
Answer:
2 moles of Methane gas will occupy 44.8 L
Explanation:
If one mole of any gas occupies 22.4 L under certain conditions of temperature and pressure, and those conditions are assumed in this question, then we comfortably solve this problem as follows;
1 mole of Methane gas ---------------> 22.4 L
2 moles of Methane gas -------------->?
Cross and multiply, 2 moles of Methane gas = 2 X 22.4 L = 44.8L
Therefore, 2 moles of Methane gas will occupy 44.8 L, if the conditions of temperature and pressure are maintained.
OPTION A IS THE RIGHT SOLUTION.
First put everything into the same measurements.
111 km = 111km
42mpg = 67.592kpg
1 U.K. Gallon = 4.546 liters
67.592/4.546 = 14.8684557853
42mpg = 14.87kpl (kilometers per liter)
1.10 euros/liter = 1.10 euros/liter
If you drive 111 km a day and go 14.87 km a liter, divide 111 by 14.87 to get about 7.46, which is how many liters you will use a day. Multiply the price, 1.10 euros, by the number of liters, 7.46, to get the daily price of gas, which is about 8.206 a day. Multiply by 7 (num of days in week) to get about 57.44
It cost about 57.44 euros for one week of gas.
I hope I'm not too late! And hopefully that is right! No guarantees lol
The Answer is C
<span> It can be separated by physical means and is uniform in composition.</span>
I believe the correct answer from the choices listed above is the third option. The ion would be Al+3. It is obvious because among the options, this is the only substance that has a charge. <span>An </span>ion<span> is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. </span>
