There are 16 ounces in a pound, so 16 / 0.110 = 145.5 ping-pong balls would weigh 1 pound. Rounded down, this means that you would need 145 ping-pong balls to equal 1 pound in weight.

No they do not.
Sure it can. But you'll need a lot a lot of ping pong balls- I believe the ratio is about 1 pound per 15 ping pong balls... then you can lift just about anything.
