To solve this problem, we must be given first the density of air at 20 degrees Celsius. Looking up online, this is equal to:
density air (20C) = 0.0012041 g/mL
so that the volume is:
volume balloon = 0.57 g / (0.0012041 g/mL)
<span>volume balloon = 473.38 mL</span>
Answer:
this is the required answer look it once
