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.
An earthquake is caused by a sudden slip on a fault. ... When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the North American Plate.
1st you need to find the mole ratio between KClO3 and O2. To find that you need to take the coefficents of each of the compounds. That gives a ratio of 2:3.
Now we find out how many each unit is:
2x = 12
x = 6
Now we multiply it by 3 to find the number of moles of O2
3(6) = 18 mol O2.
Carbon atom has 4 valence electron and can form 4 bonds with carbon and other atoms and it can also form single, double and triple bond with other carbon atoms.
So, the statement is false.
