If the tare weight of a cylinder is 19 pounds and the propane capacity is 20 pounds, to how many pounds should the cylinder be filled?

The correct answer reflects the standard practice of filling propane cylinders to a safe and effective level. In this case, the maximum capacity of the cylinder for propane is stated to be 20 pounds. However, to ensure safety and proper operation of the cylinder, it is recommended that it be filled only to about 80% of its maximum capacity.

When the cylinder is filled to this 80% level, it allows for thermal expansion of the propane and reduces the risk of overpressure, which can occur if the cylinder is filled completely. Thus, filling the cylinder to 80% of its propane capacity would mean filling it with 16 pounds of propane.

To find out the total weight that the filled cylinder would weigh, you would add the tare weight (the weight of the empty cylinder) to the weight of the propane being added. In this case:

• Tare weight: 19 pounds

• Propane to be filled (at 80% of 20 pounds): 16 pounds

Therefore, the total weight after filling the cylinder would be:

19 pounds (tare weight) + 16 pounds (propane) = 35 pounds.

This calculated total reflects a safe and compliant operation for the propane cylinder as opposed to filling it to its
