The answer will depends on the size of the bag, how much cement it makes and the thickness of the cement layer. Since you have not bothered to share these crucial bits of information, I cannot provide a more useful answer.

A 50 kg bag of cement typically covers about 0.5 to 1 square meter when used for flooring, depending on the thickness of the layer applied and the mix ratio with aggregates. For a standard thickness of 5 cm for a concrete floor, you can expect to cover closer to 1 square meter. It's important to consider the specific project requirements and mixing proportions for more accurate estimates.

The amount of cement needed per square meter for a wall depends on the type of wall and the construction method. For a standard brick or block wall, approximately 0.1 to 0.15 cubic meters of cement mortar may be required per square meter. This translates to about 150 to 225 kg of cement, assuming a typical mix. It's essential to consider the specific design and materials used for precise calculations.
That depends on how thin you spread it. If it's a meter thick, it only covers one square meter. If it's a centimeter thick, it covers a hundred square meters.
You would need 25 (5x5).
