A company advertises that it delivers helium at a gauge pressure of 1.72×10 Pa in a cylinder of volume 43.8 L. How many balloons can be inflated to a volume of 4.00 L with that amount of helium? Assume the pressure inside the balloons is 1.01×10 Pa and the temperature in the cylinder and the balloons is 25.0∘C. 2.55×10^3 3.25×10^3 1.87×10^3 3.25×10^3
