A group of students are tasked with finding the mass of a given sample. In the lab, students find the sample to have a mass of 152 grams. If the students report that their percent error is 3.82%, what is a possible accepted value for the mass for the sample?

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
