A student placed 18.5 g of glucose (C6H12O6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then
mamaluj [8]

Answer:

1.30464 grams of glucose was present in 100.0 mL of final solution.

Explanation:

Molarity=\frac{moles}{\text{Volume of solution(L)}}

Moles of glucose = \frac{18.5 g}{180 g/mol}=0.1028 mol

Volume of the solution = 100 mL = 0.1 L (1 mL = 0.001 L)

Molarity of the solution = \frac{0.1028 mol}{0.1 L}=1.028 mol/L

A 30.0 mL sample of above glucose solution was diluted to 0.500 L:

Molarity of the solution before dilution = M_1=1.208 mol

Volume of the solution taken = V_1=30.0 mL

Molarity of the solution after dilution = M_2

Volume of the solution after dilution= V_2=0.500L = 500 mL

M_1V_1=M_2V_2

M_2=\frac{M_1V_1}{V_2}=\frac{1.208 mol/L\times 30.0 mL}{500 mL}

M_2=0.07248 mol/L

Mass glucose are in 100.0 mL of the 0.07248 mol/L glucose solution:

Volume of solution = 100.0 mL = 0.1 L

0.07248 mol/L=\frac{\text{moles of glucose}}{0.1 L}

Moles of glucose = 0.07248 mol/L\times 0.1 L=0.007248 mol

Mass of 0.007248 moles of glucose :

0.007248 mol × 180 g/mol = 1.30464 grams

1.30464 grams of glucose was present in 100.0 mL of final solution.

What is the best way to eliminate poison ivy?
antoniya [11.8K]
What poison ivy looks like:
Each leaf has 3 little leaflets. It tends to grow off-white berries on the leaves in the early fall, and grows yellow-green flowers in the spring. 

Treating poison ivy:
If you have a rash from poison ivy, it is recommended to rinse your skin off with lukewarm water immediately after you notice the rash. 
Make sure to wash your clothing since the oil from the plant can stick to your clothing.
Do not scratch at the rash, as scratching will cause an infection.
If blisters appear on your skin, do not mess with them as it can prevent infection.

How to kill poison ivy:
If you find the plant, do not pull or burn it. Even if you pull it, it will still grow out of the ground since you did not eliminate the roots of it. Burning it can release <span>urushiol into the air which can be harmful.
</span>It is recommended to use a specialized weed killing spray. Always look at the ingredients in the spray and look for: Triclopyr, which fights through the surface of the plant, and also <span>glyphosate, that helps kill the roots of the plant.
</span>Once you use a spray, it will take 1-2 weeks for it to die. It will eventually turn yellowish-brownish.

Important:
 Poison ivy contains urushiol which can cause allergic reaction.
Burning poison ivy releases urushiol into the air which can also cause allergic reaction and can be harmful.
