Question

When one gram of liquid ethanol, C2H5OH(l), is burned, 29.7 kJ of heat are released. How much heat is released when 4.337 pounds of liquid ethanol are burned?

Answer 1

Answer:

58425.84 kJ is released when 4.337 pounds of liquid ethanol are burned.

Explanation:

Given that:-

When 1 gram of liquid ethanol is burnt, 29.7 kJ of energy is released.

The conversion of pounds to gram is shown below as:-

1 pound = 453.6 gram

Given mass of liquid ethanol = 4.337 pounds.

So,

4.337 pounds = 453.6*4.337 grams = 1967.2 grams

Thus,

When 1967.2 gram of liquid ethanol is burnt, 29.7*1967.2 kJ of energy is released.

58425.84 kJ is released when 4.337 pounds of liquid ethanol are burned.
