This would mean the masses of Na and Cl are 22.99g and 35.45g respectively. Therefore, the percent composition of NaCl is 39.3% sodium and 60.7% chloride.
It has no effect. If you are not tampering with the substance and just observing, nothing will change
The magnitude of the force causing this acceleration is 15 N
<u>Explanation:</u>
we know that
F=ma: According to the newton's second law
F - force acting on the object
m - mass of the object
a - acceleration
Newton's second law states that acceleration depends on force acting on the object and mass of the object.
Force is directly proportional to acceleration and mass is inversely proportional to acceleration.
here,
m = 5 kg
a = 3 m/s2
12.5 mols of glucose are in 5 liters of the 2.5 M solution.
I can’t really see the picture towards the bottom I’m sorry
