What is the mass in grams of 1.68 gal of water? The density of water is
1.00 g/mL.

To find the mass in grams of 1.68 gallons of water, we can follow these steps:

### 1. Convert gallons to milliliters (mL):
We know that:
- 1 gallon = 3.78541 liters
- 1 liter = 1000 mL

Thus:
\[
1.68 \, \text{gal} = 1.68 \times 3.78541 \, \text{L} = 6.35869 \, \text{L}
\]
\[
6.35869 \, \text{L} = 6,358.69 \, \text{mL}
\]

### 2. Use the density of water:
The density of water is given as 1.00 g/mL, meaning each milliliter of water weighs 1 gram.

### 3. Calculate the mass:
Since 1 mL of water = 1 gram, the mass of 6,358.69 mL of water is:

\[
\text{Mass} = 6,358.69 \, \text{grams}
\]

Thus, the mass of 1.68 gallons of water is **6,358.69 grams**.
