A lab group made a copper amine stock solution with a concentration of 0.02 M. A group member transfers 9.27 mL of this solution

to a 25 mL volumetric flask and dilutes to the line with water. What is the concentration of the resulting solution?

Answer : The concentration of the resulting solution is, 0.0074 M

Explanation :

Formula used :

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the initial molarity and volume of stock solution.

M_2\text{ and }V_2 are the final molarity and volume of diluted solution.

We are given:

M_1=0.02M\\V_1=9.27mL\\M_2=?\\V_2=25mL

Putting values in above equation, we get:

0.02M\times 9.27mL=M_2\times 25mL\\\\M_2=0.0074M

Hence, the concentration of the resulting solution is, 0.0074 M

When sodium hydroxide NaOH dissociates in water, the oxygen atoms on the hydroxide anions will interact with:
Inessa05 [86]

Answer:

Hydroxide ions ( OH−) are negatively charged, and the formal negative charge is on the oxygen atom. Since opposite charges attract, the oxygen atoms will interact with the positive end of water's dipole.

How many grams are in 2 moles of H₂O?
Lynna [10]

<em>Question:</em>

<h2>How many grams are in 2 moles of H₂O?</h2><h2 />

<u><em>Answer:</em></u>

<h3>One mole of H2O has a mass of (2*1 + 1*16 = 18g). We read the 1 and the 16 from the periodic table of the elements under “atomic weight” or “atomic mass”. I’ve taken the whole numbers from memory to keep it simple but you can read a more accurate value if you need a more accurate value from your periodic table. </h3><h3 /><h3>So if one mole of H2O has a mass of 18g, then 2 moles will have a mass of 18*2 = 36g.</h3><h3 />

<em>Note: * I am not responsible if you get it wrong, for you are the one who asked the question. *</em>

<u>If this helped, your welcome! Please know that I might be wrong, and if I am, I am truly sorry for that. But If you would, please make me brainliest.</u>

I hope you have a rest of your great day! If there is an issue with this question, be happy to comment. <3
