Weather balloons fly many miles high. At the ground they look like very loose bags, but they expand and fill out as the balloon goes higher. A balloon will rise as long as the wieght of the gas in the balloon is less than the weight of the air it displaces. Eventually a balloon reaches a point where the air it displaces weighs the same as the gas inside of the balloon, the balloon can't expand further, and it ceases to rise any further.
It may not pop, but just reach a position of equillibrium. It will pop only if the pressure of the gas inside the balloon exceeds the strength of the balloon before the point of equillibrium is reached.

It will float (being lighter than air) until the pressure inside is
so much greater than the pressure outside that the rubber that
the balloon is made of can't handle the strain anymore. That
will depend on how strong the rubber is that the balloon is made of.
Weak balloons will pop lower down, while strong balloons
can rise very very high indeed (like weather balloons). So
it's kind of hard to answer the question. Maybe one could make
a reasonable set of assumptions and calculate when it would happen
for a toy balloon, but I'm not sure how.

the better it is going the decrease the air tension. because of the fact the air tension is decreased, the strain interior the balloon presses out which will strengthen the quantity of the balloon. rather quickly the burden interior the balloon weighs an identical volume as exterior the balloon. meaning there is not greater buoyancy so the balloon can no longer upward push any better
