What is the molarity of 100 ml of a 30% H2O2 solution?
The molarity of a 30 % hydrogen peroxide solution is 9.8 M based on a density of 1.11 g/ml.
What is the molarity of a 30% hydrogen peroxide solution?
What is the molarity of the 30% hydrogen peroxide solution? The molarity of a 30 % hydrogen peroxide solution is 9.8 M based on a density of 1.11 g/ml.
How do you calculate how long a battery will last?
To determine how long your battery will last, calculate the battery’s total capacity and divide it by your circuit’s power. Multiply the battery’s reserve capacity by 60. With a reserve capacity, for instance, of 120: 120 x 60 = 7,200.
How do you make a 30% hydrogen peroxide solution?
The molarity of 30% H2O2 solution is 9.8 M. To make 40 mM solution, you should dilute 30% solution 245 times, i.e. mixing of 1 mL of 30% H2O2 with 244 ml of H2O will give you 245 mL of 40 mM H2O2.
What is 30% hydrogen peroxide used for?
Hydrogen peroxide is a mild antiseptic used on the skin to prevent infection of minor cuts, scrapes, and burns. It may also be used as a mouth rinse to help remove mucus or to relieve minor mouth irritation (e.g., due to canker/cold sores, gingivitis).
What does 30% H2O2 mean?
30% w/v means that you have 30 grams of compound in 1 liter solution. 0.1 molar means that you have 0.1 mole of compound in 1 liter solution. 0.1 mole of H2O2 is equal to 3.401 grams of h2o2. So, you need to take 11.3 ml of solution and dilute up to 1000 ml.
What does 30% w/w hydrogen peroxide solution actually mean?
% w/v means “weight per volume”, i.e. 30g H2O2 per 100mL (of whatever solvent). 30% (w/v) means: if you take 100 ml of that solution, it contains 30 g of H2O2. You should keep it at 4°C in a dark bottle.
How long will a 35ah battery last?
The battery can be used for 20 hours or 35 hours. This is not correct. 35 ah means the battery can deliver 35 Amps for one hour.
