Answer:
17.7%.
Answer:
Most oils and fats are less dense than water (they float) so the density is less than 1 g/ml - likely around 0.8 g/ml. Muscle sinks in water, so the density is above 1 g/ml. Muscle is at least 20% heavier than fat for a given volume. -
Answer:
Fat is bulky and lumpy so if you carry an extra five pounds of fat, you'll be lumpier than with five pounds more muscle. A five pound pile of fat will take up more space (volume) than a five pound pile of muscle; but five pounds is still five pounds. The correct way to state the muscle weighs more than fat scenario is, "Muscle is heavier by volume than fat."
A woman weighing 150 pounds with 19% fat will look much smaller (and be much healthier) than a woman at 150 pounds with 35% fat. They weigh the same, yet the composition is different. Because muscle is more dense than fat the person with less fat and more muscle will look smaller.
