Answer:
0.74M
Explanation:
Step 1 :
Data obtained from the question.
Initial concentration (C1) = 3M
Initial volume (V2) = 185mL
Final volume (V2) = 750mL
Final concentration (C2) =..?
Step 2:
Determination of the new concentration of the solution.
The new concentration of the solution can be obtained by using the dilution formula as shown below:
C1V1 = C2V2
3 x 185 = C2 x 750
Divide both side by 750
C2 = 3 x 185 / 750
C2 = 0.74M
Therefore, the new concentration of the solution is 0.74M
Answer:
B
Explanation:
The component carbon (C) has an nuclear number of 6, which suggests that all impartial carbon particles contain 6 protons and 6 electrons. In a commonplace test of carbon-containing fabric, 98.89% of the carbon particles too contain 6 neutrons, so each encompasses a mass number of 12.
Hope that helps
have a good day
Can i have brain too pls!!!
Let's think about the solution first: it's composed of water (100 g) and 35.04 grams of NaCl (in beaker for)
together it's 100+35.04=135.04
and NaCl in this solution is 35.04/135.04=25.95.
So the answer is 25.95
