Convert 0.02 g/mL to the unit g/L.
Elenna [48]
I don't know but I think that 0.02 g/mL is 20 g/L because you multiply the 0.02 by a 100. That's how you get the Gram liter

Which mixture would be best to use as a wash for removal of the alkylcatechol from skin exposed to poison ivy?water and baking s
Rudiy27

The question is incomplete. Here is hte complete question.

The components of poison ivy and poison oak that produce the characteristic itchy rash are cathecols substituted with long-chain alkyl groups. The image is attached.

If you were exposed to poison ivy, which of the treatments below would you apply to the affected area? Justify your choice.

(a) Wash the area with cold water.

(b) Wash the area with dilute vinegar or lemon juice.

(c) Wash the area with sopa and water.

(d) Wash the area with soap, water and baking soda (sodium bicarbonate)

Answer: (d) Wash the area with soap, water and baking soda.

Explanation: Alkyl is hydrophobic, which means it doesn't "mix" with water. To make it more soluble in water, soap helps to dissolve the chemical compound. As shown in the image, alkylcathecol is mildly alkaline. Baking soda is a salt that also helps dissolve it by ionizing with the -OH group, which makes it more soluble.

Although lemon juice and vinegar are acids, they are weak acids and so, won't have a strong effect on the alkylcathecol.

As said before, alkyl is hydrophobic, so plain water won't affect in any way the cathecol.

Find the number of molecules in .815 mole of O2​
Simora [160]

Answer:

4.9 × 10²³ molecules

Explanation:

Given data:

Number of molecules = ?

Number of moles of oxygen = 0.815 mol

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

0.815 mol  ×  6.022 × 10²³ molecules  / 1 mol

4.9 × 10²³ molecules

What is the molarity of a solution containing 56 grams of LiF in 959 mL of solution?
andrezito [222]

Answer:

2.25 M     <========= I do not see this in your selection of answers !

Explanation:

Mole weight of  Li F

      ( from periodic table ) = 6.94 + 18.998  = 25.938 gm/mole

56 gm / ( 25.938 gm /mole) = 2.15899 moles

2.15899 mole / (.959) L = 2.25 M
