Explanation:
Answer:
1.3x10⁻⁸ mol/L
Explanation:
<em>0.0013μmol, Calculate concentration in mol/L</em>
<em />
To obtain concentration in mol/L we need to convert the μmoles to moles and mL to liters:
<em>Moles silver(II) oxide:</em>
0.0013μmol × (1mol / 1x10⁶μmol) = 1.3x10⁻⁹ moles
<em>Liters solution:</em>
100mL * (1L / 1000mL) = 0.1L
That means concentration in mol/L is:
1.3x10⁻⁹ moles / 0.1L =
<h3>1.3x10⁻⁸ mol/L</h3>
Hydrogen has only one electron. It has one proton of nucleus and one outter electron.
Answer:Videos
For example, when oxygen and hydrogen react to produce water, one mole of oxygen ... These conversion factors state the ratio of reactants that react but do not tell ... In a typical chemical equation, an arrow separates the reactants on the left ... For example, to determine the number of mol
