To determine the mass of each compound, we need to convert them into units of moles first. We use avogadros number to do this and use the molar mass of the compounds to convert to mass.
<span>3.01 × 1023 molecules H2O ( 1 mole / 6.022x10^23 kg) (18.02 g / 1 mole) = 9.01 g
8.32 × 1020 formula units CaBr2 </span>( 1 mole / 6.022x10^23 kg) (199.89 g / 1 mole) = 0.28 g<span>
1.93 × 1026 molecules XeF6 </span>( 1 mole / 6.022x10^23 kg) (245.28 g / 1 mole) = 78610.16 g
Balanced equation: 2Fe + 3H2O → Fe2O3 +3H2
Convert g to mols:
285/55.845 = 5.1034 mols
Mole ratio of Iron and Iron (III) Oxide: 2:1
5.1034/2 = 2.5517 mols
Answer is: +113.
Nihonium<span> is a </span>chemical element<span> with symbol </span>Nh<span> and </span>atomic number 113. It has 113 protons (<span>positive </span>electric charge<span> of +1</span>). P<span>rotons, beside neutrons (neutral charge), are in the </span>nucleus<span> of every </span><span>atom. Because only protons in nucleus have charge, charge of element-113 is +113.</span>
