What does the (g)in H_(2)O (g) tell you? Measure in grams Substance is a gas Heated using gas An aqueous solution.

The notation used in chemical formulas provides specific information about the physical state of the substance. In this context, the letter in parentheses following a chemical formula denotes the physical state of the substance at room temperature. The symbols commonly used are (s) for solid, (l) for liquid, (g) for gas, and (aq) for an aqueous solution, which means the substance is dissolved in water. Therefore, when we see \( \mathrm{H}_{2}\mathrm{O}(\mathrm{g}) \), the "(g)" indicates that the substance, in this case water ( ), is in its gaseous state.
