Wheight 2 g of Tween80 and add it to 98 g of the solvent (with water = also, though not exactly: fill it up to 100 ml)
To make a 2% solution from a 25% solution, you need to dilute it. Let x ml be the amount of water needed. Using the equation for mass balance: 0.25(40) = 0.02(40 + x), solve for x to find that x = 875 ml of water needs to be added.

2 percent bromine solution typically has a reddish-brown color.
As blue is a primary colour, it cannot be made by mixing 2 colours, however it can be used to make other secondary colours. Cyan and magenta mix to make blue. 100 percent cyan, 100 percent magenta make a good deep two-color blue. Normally I throw a little black and maybe some yellow into my blue.
To make a 2% sodium hypochlorite solution from a 12% solution, you can set up the equation: 12% solution * x litres = 2% solution * 100 litres Solving for x, you get: x = (2% solution * 100 litres) / 12% = 16.67 litres Therefore, you would need 16.67 litres of the 12% sodium hypochlorite solution to make 100 litres of a 2% solution.
Tween80 is added to India ink for fungal wet mounts to reduce surface tension and help disperse the ink evenly. This allows for clearer visualization of fungal structures such as hyphae and spores. Additionally, Tween80 helps prevent clumping of the ink, making it easier to distinguish individual fungal elements.
You make 1 percent to a decimal which is .01(You make it into a decimal by dividing 1 by 100) then you make 1/2 percent into a decimal which is 0.5. Then you multiply .01 and .5 and it equals 0.005.
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
You make an equation: 0.02*X=16 Which means 2 percent of X is 16.
50% = 1/2

5.9% because you move the decimal over 2 spaces to the right to make it a percent.
2%
Move the decimal point 2 places to the right to make 550 to percent. 550.00 * 100% = 55000%
You move the decimal 2 places over.
