The combustion of one mole of liquid ethanol, CH3CH2OH, produces 1367 kJ of heat. Calculate how much heat is produced when 235.0
deff fn [24]

Answer:- 6984 kJ of heat is produced.

Solution:- From given information, 1367 kJ of heat is produced by the combustion of 1 mole of ethanol. We are asked to calculate the heat produced by the combustion of 235.0 g of ethanol.

Let's convert given grams to moles and multiply by the heat produced by one mole of ethanol to get the total heat produced. Molar mass of ethanol is 46 grams per mole. The set will be:

235.0g(\frac{1mole}{46g})(\frac{1367 kJ}{1mole})

= 6984 kJ

So, 6984 kJ of heat is produced by the combustion of 235.0 g of liquid ethanol.

If 0.25 liters of solution contains 0.030 moles of KOH what is the molarity of the solution?
sdas [7]

Answer:

The molarity of the solution is 0,12 M.

Explanation:

We calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case KOH) in 1000ml of solution (1 liter):

0,25 L solution----- 0,030 moles of KOH

1 L solution----x= (1 L solution x 0,030 moles of KOH)/0,25 L solution

x= 0,12 moles of KOH ---> <em>The solution is 0,12 M</em>
