Answer:
Volume of the concentrated solution, which is needed is 103.30 mL
Explanation:
Let's apply the formula for dilutions to solve the problem
Conc. Molarity . Conc. volume = Dil. Molarity . Dil volume
12.1 M . Conc. volume = 2.5 M . 500 mL
Conc. volume = (2.5 M . 500 mL) / 12.1M
Conc. volume = 103.30 mL
Answer:
it is B because the other answers logically dont fit in
First, find out how many years are in a decade. There 10 years per decade. So in 5 decades, that makes 50 years. Then multiply 50×12 because there are 12 months in a year. So there are 600 months in 5 decades.
Yes and no he said that all atoms of a given element are identical in mass and properties.
