The average body is 60% water
65%. But the amount varies somewhat.
You lost 10 pounds of water weight.
That depends on what substance is in the gallons. If it's water, then they weigh about 37.6 pounds. If it's gold, then they weigh about 718 pounds. If the gallons are empty, then they have no weight at all.
no, it will weigh heavier because it will dry into cement when mixed with water and the weight of water will add to the weight of the concrete.
A gallon of water weighs about 8.34 pounds. If you have a good sized bucket with a gallon of water in it and you put a 5-pound fish in the bucket, you'll have a bucket that weighs about 13.34 pounds (plus the weight of the bucket). That's as long as the bucket doesn't overflow. The fish will (usually) be neutrally bouyant in the water, and it will be essentially weightless in that water. But its weight will add to that of the water in the bucket. No, it won't weigh 15 pounds, but it will weigh in as suggested. However, the weight of the water itself will not change.
You can't; but you can measure the amount of it in milliliters and liters. If you really want to find an ounces or pounds weight, put it in a container, weigh the empty container first, then add the water and weigh and then subtract the weight of the container.
it depends on how much you sweat during the workout, 350 calories doesnt weigh much, but water weight does
On Mars, you weigh 37.7% as much as you would on Earth. If you weigh 100 pounds on Earth, you weigh only 37.7 pounds on Mars. If you weigh 150 pounds on Earth, you weigh only 56.6 pounds. The equation is .37 x Earth weight = Martian weight.
A large one would weigh around 600 pounds.
On Mars, you'd weigh 76.38 pounds.
8.35 pounds per gallon 8.35 * 60 = 501 pounds
10.02 pounds. Take the weight and multiply it by .167 to find the "Moon weight"
