Answer:
The answer to your question is None of your answers is correct, maybe the data are wrong.
Explanation:
Data
Concentration 1 = C1 = 1 M
Volume 2 = 5 ml
Concentration 2 = 0.05 M
Volume 1 = x
To solve this problem use the dilution formula
Concentration 1 x Volume 1 = Concentration 2 x Volume 2
Solve for Volume 1
Volume 1 = (Concentration 2 x Volume 2)/ Concentration 1
Substitution
Volume 1 = (0.05 x 5) / 1
Simplification
Volume 1 = 0.25/1
Result
Volume 1 = 0.25 ml
CH4 : Mr. 12+(1x4) =16
C= 12
12/16 x 100 =75%
Answer:
your answer is 30f
Explanation:
The coldest possible temperature, or absolute zero, is -273.15 degrees Celsius, or 0 degrees Kelvin. So, 10 degrees Celsius (and this shouldn't be taken too literally) is in fact only about 1.8 per cent warmer than 5 degrees, and 30 degrees is only about 5.2 per cent warmer than 15 degrees.
