Zinc mass if a 1.85 g mass of zinc produces 475 ml of gas and your balloon weighs 0.580 g and the room temperature is 21.5°c. calculate the amount of zinc needed to produce enough gas to get your balloon airborne by adding 1 ml to the required balloon volume so that its density is less than that of the surrounding air. (hint: complete balloon volume calculation as you did in question 2 above)
