Converting % solute concentration to mg/l; liquids
Hi,

I'm new and need help with a formula to convert 0.002% hydrogen peroxide/volume (968 fl oz) to mg/L.

Thanks

Step 1: 0.002% = 0.00002
Step 2: 0.00002*968 fl oz = 0.01936 fl oz
Step 3: 0.01936 fl oz \$\displaystyle H_{2}O_{2}\$ = ?? mg \$\displaystyle H_{2}O_{2}\$
Step 4: 1 fl oz = ?? L

Fill in the balanks. Then what?

Thanks TK
Step 3: 0.01936 fl oz http://www.mathhelpforum.com/math-he...c592e2a3-1.gif = 580.8 mg http://www.mathhelpforum.com/math-he...c592e2a3-1.gif
Step 4: 1 fl oz = 0.03 L

Goal: to supplement dissolved oxygen with H2O2 in transport water for aquarium fish transport and not cook gills, corneas and mucus membrane in the process.

I really appreciate your time and help.

Correction
I believe that should be: 5,808.0 mg http://www.mathhelpforum.com/math-he...c592e2a3-1.gif/L for the 0.002% solution... not 580.8 mg/L.
