You are watching: If the percent by volume is 2.0 and the volume of solution is 250ml what is the volume
no of moles in 4 grams that H2=4/2=2
the reaction shows that 2 moles of H2 react v 1 mole of O2 to produced 2 mole H2O
now no of moles in 36grams that H2O=36/18=2
therefore he needed 1 mole of O2 to create 36 grams the H2O and also 1 mole the oxygen is same to 32 grams of O2
Actually bromine have 35 electrons once it is neutral, and also if the variety of electrons is enhanced by 1 the gains a relative negative charge of 1.
