In Golf there is no limit to the number of balls used. Depending on difficulty of the course and a players experience one single golfer could use as many balls as they have in their bag at the start of play.
== == You can carry as many golf balls as you want.
You would find that a tour pro would use between 12 and 20 golf balls for a four round tournament.
A tour pro would have around a dozen golf balls in there bag per round, just in case. But it is completely up to the player.
It is unlimited
There is no limit, but when a player runs out of golf balls, they are deemed unfit to continue, so they are disqualified.
I think there is no such rules that tell that can disqualify any player that plays with too many golf balls.
106 golf balls
You can carry as many as you like. It doesn't matter as they count on strokes not balls. However, you are expected to use the same ball from tee to the hole unless you loose it, or it becomes unplayable due to damage. You can play a new ball on every hole if you wish.
The R&A, which is the ruling authority for most golfing tournaments worldwide, maintains a list of balls that conform to tournament regulations. Many different coloured balls are included in this list - there is no rule that states a ball has to be white.
356,000 million golf balls ;)
Approximately 5 golf balls could fit.
