Text Solution

AI Generated Solution

To calculate the number of gram molecules contained in the given masses, we will use the formula: \[ \text{Number of gram molecules} = \frac{\text{Weight in grams}}{\text{Gram molecular weight}} \] We will calculate the gram molecular weight for each compound first, and then use the formula to find the number of gram molecules. ...
