The answer is 2 blowholes for whales.
A gray whale's respiratory system consists of blowholes located on the top of its head, which it uses to breathe air at the water's surface. The blowholes connect to the lungs, allowing the whale to exchange gases necessary for respiration. Gray whales are mammals and require oxygen from the air to survive.
The killer whale is a toothed whale, not a baleen whale. Killer whales have a diverse diet that includes fish, seals, and even other whales, and they use their teeth to catch and consume their prey.
Order Cetacea is organized into two suborders: Mysticeti (baleen whales) and Odontoceti (toothed whales). Mysticeti includes whales that filter feed using baleen plates, while Odontoceti includes whales with teeth for hunting. Each suborder further divides into families, genera, and species based on specific anatomical and genetic characteristics.
They need a blowhole to breathe with. They come up to the surface out of the water and "breathe in air" through the blow-hole. Then they can go back down into the water for a period of time until they need to re-surface for more air.
Whales sense sound waves through a fatty, oval shaped organ located in the forehead of all odontocetes (toothed whales). It is believed to be a bioacoustic component, meaning it focuses echolocation so as to use the least amount of energy to communicate.
Usually they have one Baleen whales have two blowholes. Toothed whales have only one.

There are currently 88 known species of whales, dolphins, and porpoises that have blowholes, so there are potentially 88 blowholes in the world.

All types of whales have blowholes because they need them to breathe. As we have noses, whales have blowholes. Porpoises and dolphins have blowholes as well.
baleen whales are larger than toothed whales. Baleen whales have two blowholes on the top of there heads.Baleen whales are solitary most of the time and they eat small fish and plankton.

Whales and dolphins.
All whales have a blow hole.

Yes all whale have blowholes because they are mammals.
