Answer:
42.64 M
Explanation:
Step 1: Given data
- Moles of HCl (solute): 8.1 mol
- Volume of the solution: 189.98 mL
Step 2: Convert the volume of the solution to liters
We will use the relationship 1 L = 1,000 mL.
Step 3: Calculate the molarity of the solution
The molarity is equal to the moles of solute divided by the liters of solution.
Moles of calcium metal used = 100/40.1=2.5
Moles of HBr need to react = 5 moles
As the molar ratio is 1 is to 2 among them
so
Moles=molarity x volume
5=2.25 x volume
volume=2.22 litres of HBr required for this reaction
ANSWER IS 2.22 LITRES
In the summer, in the southern hemisphere. when it is summer is the northern, it is winter in the southern. all year along, the most sun hits the equator, but when it is winter in the northern hemisphere (thats when Alaska goes dark because of no sun) there is summer in the southern Hemusphere such as continents like south america, india, africa, and places like that :)
