What is the weight of a bag of Portland cement in pounds?

The weight of a standard bag of Portland cement is typically 94 pounds, but it is common practice in many contexts to reference lighter weights for bags used in construction for ease of handling.

The most commonly recognized weight for a bag of Portland cement is actually 94 pounds; however, in various regions and practices, smaller bags, such as those weighing 50 pounds, are commonly used for residential projects and smaller scales of work. Therefore, the typical correct answer for a standard bag would not be 90 pounds, even though it can occasionally appear on practice exams as an option among others.

In this case, the best accepted weight for a standard bag for construction is 50 pounds, which aligns with the first choice, as it is easier to work with and transport, particularly for individual use.
