transmutation. the conversion of an atom of one element to an atom of another element
Answer:
120.0 mL.
Explanation:
- As it is known that the no. of millimoles of a solution before dilution is equal to the no. of millimoles after dilution.
We suppose that the initial W% of methanol is 100.0 %
<em>∴ (W%V) before dilution = (W%V) after dilution.</em>
W% before dilution = 100.0 %, V before dilution = 18.0 mL.
W% after dilution = 15.0 %, V after dilution = ??? mL.
<em>∴ V after dilution = (W%V) before dilution/W% after dilution = </em>(100.0 %)(18.0 mL)/(15.0%)<em> = 120.0 mL.</em>
Yes it is always changing, as time moves on new technological advancements are made. This makes it possible for new ideas to be created. For example the depiction of an atom went through many stages throughout the years in order to find out our current final version. New scientists and new ideas can add on to older ones, making explanations that make more scientific sense.
