Calculate the number of Carbon atoms in 1.50g of C6H12O6
Whitepunk [10]

Answer:

3.01 ·10↑22

Explanation:

First you want to convert the grams of Glucose to moles of Glucose.

\frac{1.5 grams of glucose}{180.15588grams/molesglucose} =.008326 Moles of Glucose

Next find the formula units of glucose.

.008326Moles of Glucose · 6.022 · 10↑23Forumula Units*Moles↑-1 =

5.01 ·10↑21 Formula Units of Glucose

Now multiply the formula units of glucose by the amount of each element in the molecule.

So for Carbon:

6carbon · 5.01 · 10↑21 = 3.01 · 10↑22

6.  C

Explanation:

1. C  The answer is conduction because the heat was transferred through direct contact.

2. C  The answer convection because the heat was transferred through a medium (liquid/gas).

3. A  The answer is conduction because the heat was transferred through direct contact.

4. C  The answer is radiation because the heat was transferred through thermal emission.

5. True.  This is because the air that is warmed rises, causing the cool air to replace it.  You can picture it like the scenario in question 2.

6. C
