Imagine that you work at a company that prepares chemical solutions. You are asked to label a solution to sell to different customers. One customer is a hospital, another is a chemistry lab at a university, and a third is a physics lab at a university. You added 900 kg of NaCl in a 100-liter container and filled it with water to a volume of 100 liters. Assume standard (STP) conditions.
Determine the following:
- Mass percentage of the solution for the customer in the hospital
- Molarity for the customer in the chemistry lab
- Molality for the customer of the physics lab
