I have a very dummy question pertaining to my chemistry lab. I need to find the moles of I2 added to a vitamin C sample. I'm aware the formula for finding moles is: moles = mass (g)/molar mass. However, how am I suppose to find moles from a liquid? Do I convert the mL of liquid to grams and solve for moles that way? For example, I added 30mL of I2 to an unknown sample containing vitamin C until it was neutralized.
The Time Value of Money concept says that a dollar received today is worth more than a dollar received in the future. If you receive money two years from now...
Money today is fiat money, a symbol of value created by the human imagination with no intrinsic value of its own. A coin or paper currency note has value because people accept it as a symbolic medium of exchange. The economic value of money as measured by its purchasing power is a subject of economic theory. However economics does not explain how individual human beings and societies came to accept symbolic money as a medium of exchange or store of value. The process of according value to a symbol is psychological and social.
