Answer:
2.00 M
Explanation:
The concentration of a solution is given by

where
m is the mass of solute
V is the volume of the solution
At the beginning, the solution has:
M = 6.00 M is the concentration
V = 100 mL = 0.1 L is the volume
So the mass of solute (HCl) is

Then, the HCL is diluted into a solution with volume of
V = 300 mL = 0.3 L
Therefore, the final concentration is:

Answer:
Take the measuring cylinder and measure its mass, in grams, as accurately as possible.
Take the measuring cylinder off the balance and add the water carefully. Put the measuring cylinder back on the balance. Measure and record the new mass .
Repeat the procedure, recording the volume and total mass, until the measuring cylinder is full. Then, for each volume calculate the mass of the liquid alone.Repeat steps 1 to 3 Draw a graph of mass of liquid against volume . Calculate the density of each liquid from the gradient of its graph line.
Explanation:
The answer is A- single bonds made by 1 atom to 3 other atoms within a molecule
