nucleus > brain
mitochondria > digestive system
Explanation:
To see the mole to mole ratio. If you have this then you see how many moles are used for other reactants/products in the equation
The properties of aluminium include low density<span> and therefore <u><em>low </em></u></span><u><em>weight</em></u>, <u><em>high strength</em></u>, <u><em>superior malleability</em></u>, <u><em>easy machining</em></u>, <u><em>excellent corrosion resistance</em></u> and <u><em>good thermal and electrical conductivity</em></u><span> are amongst aluminium's most important properties. <u><em>Aluminium is also very easy to recycle.</em></u>
Hope this helps:D

Answer:
The concentration is 0.036 mg/mL
Explanation:
Concentration = 0.2 mM = 0.2/1000 = 2×10^-4 M = 2×10^-4 mol/L × 180,000 mg/1 mol × 1 L/1000 mL = 0.036 mg/mL
