An unknown alcohol is analyzed by freezing point depression. The unknown is either methanol(CH3OH) ethanol(C2H5OH) or propanol (C3H7OH). A solution of 10.187g of the unknown and 100 mL of water freezes at -4.2C. What is the identity of the alcohol? I just don’t know where to plug in the molar masses into the equation

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
