The answer is false because it goes in a full 360 degree circle
Answer:
0.15 (M) of NaCl
Explanation:
An isotonic solution is defined as the solution having the same osmolarity, or the same solute concentration, as the another solution. If the two solutions are to be separated by any semipermeable membrane, then water will start flowing in equal parts from each solution and also into the other.
In the context, since it is given that the red blood cells exerts the same osmotic pressure as a 0.15 (M) of NaCl solution.
Thus, 0.15 (M) of NaCl is a isotonic solution.
Answer:
KCI is rhe solute in a homogeneous mixture
Science affected our lives at the beginning of this pandemic.
Explanation:
Although scientists did study the virus to see how deadly it is the pandemic kept spreading. The spreading of the virus was not the scientist's fault it was the citizens' fault. They now found a vaccine that took hard work and a short amount of time.
Answer:
The molarity of the solution is: 2 M
Explanation:
We calculate the weight of 1 mol of NaOH:
Weight 1 mol NaOH= Weight Na + Weight 0 + Weight H= 23 g+16g+ 1 g= 40g/mol
The molarity is the quantity of moles in 1000ml (1 liter) of solution:
0,5liter-----40 grams NaOH
1 liter----x=(1 liter x 40 grams NOH)/0,5 liter = 80 grams NaOH
40 grams----1 mol NaOH
80 grams----X=(80 grams x 1 mol NaOH)/40 grams= 2 mol NaOH--> 2M
