Answer:
The log will float on the water because its density is lower than the liquid, so it will stay at the top due to Archimedes' principle.
The molarity of the NaCl in the 250 ml slat solution is 2.8M.
<h3>What is molarity?</h3>
The molarity of a solution is defined as the concentration of a solute per unit volume of the solution.
Given, the volume of the solution is 250 ml converted into l 0.25
The number of moles of NaCl is 0.70.
By the formula of molarity

Thus, the molarity is 2.8 M.

Answer:
<h3>The answer is 6.71 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

f is the force
m is the mass
From the question we have

We have the final answer as
<h3>6.71 m/s²</h3>
Hope this helps you
I think it’s either a or b
Explanation: He made the atomic number instead of atomic mass. This fixed the discrepancies with elements such as tellurium and iodine.
