Find the new concentration of a solution if 25.0 ml of water is added to 125.0 ml of 0.150 m nacl solution. what is the final volume? ml

Answer : The correct answer is New concentration = 0.125 M and final volume = 0.150 M

Given :

Molarity of NaCl solution = 0.150 M volume of NaCL solution = 125 mL

Volume of water added = 25 mL

1) Final volume = ? 2) New concentration = ?

1) To find the final volume :

New volume = volume of NaCl solution + volume of water added

= 125 mL + 25 mL

= 150 mL

Converting this final volume from mL to L

1 L = 1000 mL

Final volume = 0.150 L

2) To find new concentration :

Following steps can be used :

a) To find mole of NaCl :

Mole of NaCl can be calculated using molarity formula . Molarity can be defined as mole of solute present in Liter of solution (volume ) .It represents Concentration of solution . It used unit as M or . It can be expressed as :

Molarity of NaCl solution = 0.150

Volume of NaCl solution = 0.125 mL or 0.125 L

Plugging these values in molarity formula

Multiplying both side by 0.125 L

Mole of NaCl = 0.01875 mol

b) To find New concentration :

Since the mole of NaCl remians same when water is added . Hence new concentration ( molarity )can be calculated using mole of NaCl and final volume .

Mole of NaCL = 0.01875 mol

Final volume = 0.150 L

plugging values in molarity formula :

New concentration = 0.125 M

that's just how they are

explanation:

you can't control another persons decisions, all you can do is ask that they respect yours. relationships are hard because you have to put the effort into making sure that another person feels seen, heard, and loved. as time goes on, it gets easier, you learn how to do these things without thinking. loving them becomes as easy as breathing, but every relationship will have fights, and sometimes it'll feel like you're drowning, but as long as you can talk it out and compromise, because that's truly what loving another person is, is compromise, then you'll be okay. movies and tv shows have glamorized and romanticized (pardon the pun) what a relationship would be like. real relationships aren't perfectly timed kisses in the rain, zero fights until one big one ends everything, 6 month anniversaries. real relationships are sleepy confused kisses when one person has to leave for work earlier than the other,   real relationships are having small disagreements, real relationships are messy and confusing, real relationships is knowing that even if you're relationship may not last forever and this may not be the person you're going to spend the rest of your life with, that you love them, and you would do anything to see them happy. so yes, relationships are difficult, but so are many other things, relationships can be amazing but also stressful, and not just romantic i'm also talking about platonic relationships (although the primary example here was romantic) sometimes is best to leave friendships behind, so remember, always do whats going to you be happy in the long run.
