how many grams of BaO are in 1L of a 2.0 aqueous BaO solution (MW BaO = 153.3g/mole)?

To find out how many grams of BaO are in 1L of a 2.0 aqueous BaO solution, we need to use the given information about the molar mass of BaO (153.3 g/mol) and the concentration of the solution (2.0).

First, let's convert the concentration (2.0) to moles per liter (mol/L). This can be done by multiplying the concentration by the molar mass of BaO:

2.0 mol/L × 153.3 g/mol = 306.6 g/L

So, there are 306.6 grams of BaO in 1L of the 2.0 aqueous BaO solution.
