Explanation:
The nitrate anion is a univalent (-1 charge) polyatomic ion composed of a single nitrogen atom ionically bound to three oxygen atoms (Symbol: NO3) for a total formula weight of 62.05. Lead Nitrate is generally immediately available in most volumes.
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>
When you put salt in water, the positive ions gravitate toward the negative sides of the water molecules while the negative ions move towards the other sides. In this way, each water molecule disrupts the lattice structure, and the result is a solution of free ions suspended in water. As more salt is dissolved, sodium and chlorine ions bump into each other and re-combine into crystals of salt.
