Answer:
E) All three samples have the same number of hydrogen atoms
Explanation:
The statements are:
A) Sample A has more hydrogen atoms than sample B or sample C.
B) Sample B has more hydrogen atoms than sample A or sample C.
C) Sample C has more hydrogen atoms than sample A or sample B
D) Both samples A and C have the same number of hydrogen atoms, but more than in sample B.
E) All three samples have the same number of hydrogen atoms
Hydrogens in sample A are:
180g × (1mol Glucose / 180.156g) × (12mol H / 1 mol Glucose) =<em> 12 moles of H</em>
Hydrogens in sample B are:
90g Glucose × (1mol Glucose / 180.156g) × (12mol H / 1 mol Glucose) =<em> 6 moles of H</em>
90g mannose× (1mol Mannose / 180.156g) × (12mol H / 1 mol Glucose) =<em> 6 moles of H</em>
<em>Total moles: 12</em>
Hydrogens in sample C are:
180g × (1mol Mannose / 180.156g) × (12mol H / 1 mol Glucose) =<em> 12 moles of H</em>
<em />
Thus, right answer is:
<em>E) All three samples have the same number of hydrogen atoms</em>

Answer:
Total Mass of daily drug used = 144 Kg
Explanation:
Total weight of the individuals =
180lbs * 10000 = 1.8 * 10^6 lbs
Since the drug is to be given 8 mg for every 100 lbs;
number of 8 mg doses = 1.8 * 10^6 / 100 = 1.8 * 10^4 doses
Total mass of the doses = 1.8 * 10^4 * 8 mg = 1.44 * 10^5 mg.
We divide the value above by 1000 to convert to Kg.
Therefore, total daily mass of drug used = (1.44 * 10^5)/1000 = 144 Kg
False because a copper coin is a solid but can harness electricity wich is an energy
