Expressing amounts of energy in different energy units is necessary to solve many chemistry problems.
For practice, complete the following table.
The Joule (J) is the SI unit of energy.
The calorie (cal) is the amount of energy needed to raise the temperature of 1 g of water by 1°C.
1 cal = 4.184 J
The British Thermal Unit (BTU) is the amount of energy needed to raise the temperature of 1 pound of
water by 1°F. 1 BTU = 1055 J

In 2019, the United States burned enough coal to supply 1.1 x 1019 J of energy. Assuming that coal is roughly 100% carbon, how many molecules of carbon dioxide did the U.S. produce by burning coal in 2019? Less than 1036 molecules of carbon dioxide.

The manufacturers of the aspartame-containing sweetener claim that one packet of their sweetener provides the same sweetness as two packets of table sugar (sucrose). The mass of two packets of table sugar is roughly 6 times greater than the mass of one packet of the sweetener. (In other words, 1 g of sweetener has the same sweetness as 6 grams of sucrose.) Based on this information and your experimental results (mg Aspartame / g Sweetner = 78.65), determine how many times sweeter aspartame is than sucrose (find the grams of sucrose that has the same sweetness as 1 g of aspartame).arrow_forwardAsking for Q 9arrow_forward
