To find the density of the liquid in g/mL, we need to follow these steps:<br /><br />1. Convert the weight of the flask when filled to grams:<br /> Weight of the flask when filled = 4536.0 g<br /><br />2. Calculate the weight of the liquid alone:<br /> Weight of the liquid = Weight of the flask when filled - Weight of the empty flask<br /> Weight of the liquid = 4536.0 g - 4.0 lbs * 453.6 g/lb<br /> Weight of the liquid = 4536.0 g - 1814.4 g<br /> Weight of the liquid = 2721.6 g<br /><br />3. Convert the volume of the liquid to milliliters:<br /> Volume of the liquid = 2.0 gal * 3.785 L/gal * 1000 mL/L<br /> Volume of the liquid = 7570 mL<br /><br />4. Calculate the density of the liquid:<br /> Density = Weight of the liquid / Volume of the liquid<br /> Density = 2721.6 g / 7570 mL<br /> Density ≈ 0.36 g/mL<br /><br />Therefore, the correct answer is option D: 0.36 g/mL.
