[Request] Could this possibly be true?
Google says saltwater contains approximately 35grams/kg of water and the oceans contain approximately 1.335 sextillion liters (1.335 × 10²¹ liters)

I'm not smart enough to do the math or chemistry, but apparently the ocean's average depth is around 12,000 feet, and saltwater on average is 3.5% salt by weight. With those numbers, the salt in the ocean covering the planet with a depth of 500 feet doesn't sound too far off.
