(1.67€/1.00kg)•($1.33/1.00kg)•(2.20lb/1.00kg)=$4.88642/lb
The final rounded answer should be $4.89 per pound
Molar mass:
O₂ = 32.0 g /mol CH₄ = 16.0 g/mol
2 O₂ + CH₄ = CO₂ + 2 H₂O
2 x 32 g O₂ ---------------> 16 g CH₄
100 g O₂ ------------------> ( mass of CH₄)
mass of CH₄ = 100 x 16 / 2 x 32
mass of CH₄ = 1600 / 64
= 25 g of CH₄
hope this helps!

Answer:
Avogadro's number is a proportion that relates molar mass on an atomic scale to physical mass on a human scale. Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA.
Explanation:
<span>THE HIGHEST CONCENTRATION OF HYDROGEN IONS IS LOCATED IN THE INTER-MEMBRANE SPACE. HYDROGEN IONS REACH THE INTER-MEMBRANE SPACE THROUGH PROTEIN CHANNELS EMBEDDED IN THE MITOCHONDRIAL MEMBRANE. THE MAIN FUNCTION OF INTER MEMBRANEIS OXIDATIVE PHOSPHORLATON. ENERGY IS REQUIRED TO MOVE THE HYDROGEN IONS ACROSS THE MEMBRANE BECAUSE THE HYDROGEN IONS ARE MOVING AGAINST THE CONCENTRATION GRADIENT. H+ GOES AGAINST THE CONCENTRATION GRADIENT THE USE OF THE GRADIENT TO DRIVE ATP SYNTHASE. HYDOGEN IONS DRIVE ATP SYNTHASE IN PHTOSYNTHESIS. THIS HAPPENS WHEN HYDROGEN IONS GET PUSHED ACROSS THE MEMBRANE CREATING A HIGH CONCENTRATION INSIDE THE THYLAKOID.</span>
