Two. Take 3 balls and 3 balls. Leave 2 on the table. If the 3 and 3 balance set them aside and weigh the remaining 2 balls and you know which one is heavier. Done. If they don't balance, take the heavier 3, place one ball on the table and balance the other 2. If they balance, the one on the table is heavier. Done. If they don't, you know which one of the two is heaver. Done.

What is heavier the density of a bag of styrofoam balls or the density of a bag of stones?
The bag of stones is heavier because stones have a much higher density than styrofoam balls. Density is mass divided by volume, so the weight of the material is determined by the mass. Stones are denser and therefore heavier than styrofoam balls of the same volume.
If you have 7 tennis balls 1 is heavier than the others and a balance How do you find which one is the heaviest only using the balance twice?
Divide the balls into 3 groups of 2, 2, and 3. Weigh the group of 2 balls against each other. If they balance, then the heavier ball is in the group of 3, in which you weigh 2 of the 3 balls to identify the heaviest. If the group of 2 balls doesn't balance, then you weigh those 2 balls to identify the heavier one.
How can you tell which of three balls is the lightest or heaviest using a simple balance that consists of two pans?
To find the lightest ball, compare two balls on the balance. If they are equal, the third ball is the lightest. If not, the lighter of the two on the balance is the lightest ball. To find the heaviest ball, follow the same process but compare balls to find the heaviest one.

If you have eight balls all of the same size.seven of them weigh the sameand one of them weighs slightly more.How can you find the ball that is heaviest in least amount of attempts?
One way to find the heaviest ball in two attempts is to split the balls into two groups of 4 each and weigh them against each other. Whichever group is heavier will contain the heavier ball. Then, take the heavier group of 4 balls and weigh two of the balls against each other. If one ball is heavier, it will be the heaviest ball. If they weigh the same, the third ball left out is the heaviest.
