Answer:
1. Not to have enough salt water on the foil
2.not cleaning the foil well to remove interfering materials
The molarity = 0.454 M
<h3>Further solution</h3>
Given
Volume = 3 L of solution
mass = 140 g of NaBr
Required
The molarity
Solution
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
mol of NaBr :
= mass : MW
= 140 g : 102,894 g/mol
= 1.361
Molarity :
= 1.361 mol : 3 L
= 0.454 M
Answer:
Back down to earth
Hot air balloons don't have pre-planned landing spots due to the fact they travel where the wind takes them. Instead, our pilots will look for a suitable open space and bring their balloon to land in a safe and controlled manner, fully compliant with aviation law.
