The element used to paint the skin to prevent infection from cuts and scratches is iodine.
The unit "m" in this given is used to refer to molality which is equal to the number of moles of the solute divided by the mass in kg of the solvent. If we let x be the mass of iodine, the equation for molality then becomes,
molality = (x / 253.8) / ((950 mL)(1.594 g/mL)(1 kg/ 1000 kg)
0.75 = (x / 253.8) / 1.5143
The value of x 288.247 g
Answer: 288.25 g
Answer: 32.9 Liters
Explanation:
To calculate the moles, we use the equation:
1. moles of 
2. moles of 
P = pressure of the gas = 1.20 atm
R = Gas constant = 
T = temperature of the gas = 
According to stoichiometry:
11 moles of oxygen reacts with 4 moles of 
Thus 2.02 moles of oxygen reacts with =
moles of
Thus oxygen acts as limiting reagent and is excess reagent.
As 11 moles of oxygen gives = 8 moles of 
2.02 moles of oxygen gives =
moles of
P = pressure of the gas = 1 atm (at STP)
R = Gas constant =
T = temperature of the gas = 
(at STP)
Thus volume of (at STP) formed from the reaction is 32.9 L
I believed he was credited with making, subatomic particles, isotopes and electrons. Joseph John Thomson was credited with the discovery and identification of the electron, and with the discovery of the first subatomic particle in 1897. He also discovered isotopes, and invented a mass spectrometer and was awarded the Nobel Prize in physics in 1906.
