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...
Investopedia explains Present Value (PV). This may sound confusing, but it really is not. The basic idea is that receiving $1,000 now is worth more than receiving $1,000 five years from now, because a person who has money today can invest it and receive an additional return over the five years.resent value of money is important in calculating bond yields, the value of annuities, and many other transactions. It is also used in comparing the value of two amounts of money existing in different times.
