The heat being released is calculated by multiplying the amount of NaOH used for making the solution. We are given a delta H that is equal to -445.1 kJ / mol. This value is per mole NaOH. Calculation is as follows:

-445.1 kJ / mol NaOH (1.0 g NaOH ) ( 1 mol NaOH / 40 g NaOH ) = -11.1 kJ

Why do gases deviate from ideal gas behaviour?
UNO [17]

The ideal gas behavior gets deviated because of the real gases. The particles in the gas occupy finite space and exert interactive forces between themselves.  

Explanation:

An ideal gas behavior is at low temperature and at high pressure. According to kinetic theory, the ideal gases "do not occupy space" and there is "no interaction" among the gas molecules. But practically while applying the gas laws this is not the actual case.

<u>Ideal gas equation: </u>

To make a 3.50 M solution, how many moles of solute will be needed if 11 liters of solution are required?
nignag [31]

Answer:

38.5 moles of solute

Explanation:

3.5 M = moles / 11 Liters

moles = Molarity * Liters

moles = 3.5 M * 11 Liters

moles = 38.5
