Answer published by the source. Consult the official source to check your work against its answer.

One of the isotopes was extracted from another isotope through boiling of the liquid as light molecules evaporate and heavy molecules are concentrated at the bottom. Considering that the initial volume is 2L and only half is evaporated in each boiling and the coefficient of division for heavy molecules is 1.45. How many times (rounded to a whole number) should it be evaporated without refilling so that the concentration will increase 10 times? (initial concentration is 0.016%)
