## How to figure out 1 : 10 dilution for a 16oz container?

For 1 to 10, you will have 11 total parts. So for 1 part = 16/11. For 10 parts use 10*16/11=160/11. 16oz-1.45= 14.55 oz water. 1 part concentrate plus 1 part dilution equals 11 parts total. If you want your final volume to be 16 oz, divide 16 oz by 11. That equals roughly 1.45 oz of concentrate and 14.55 oz of dilution.

How to dilute 10x mops in sterile water?

Use sterile water to dilute 10X solution. Store at room temperature. To Produce 1X MOPS Solution (0.2M): Simply Add 4.18gm of MOPS to 1L of Sterilized Water. To Produce 10X MOPS Solution (0.2M): Simply Add 41.8gm of MOPS to 1L of Sterilized Water.

How many parts kodagraph to 7 parts water?

On a bottle of Kodagraph thats 30 years old it says 1:7 and also says 1 part Kodagraph to 7 parts water. Thus it clearly states what the colon is ratioing; so folks know and do not assume. With larger ratios it really doesnt matter as much whether the weed eater really sees 1/49; 1/50 or 1/51 parts oil.

### Why is Kodak using the wrong dilution method?

The way Kodak uses the colon; ie parts stock : water parts is in books from the 1920’s and older; thus there is no reason for folks to inject the wrong dilution method; or even say Kodak is wrong. The error is minor for large dilutions ratios; and the error grows large with dilution that uses less water.
