    Yeah this helped a lot thank you Chet!

    Calculating the Volume of a Mixture of Ethanol and Water

    Ok I just fixed my errors and I got the final volume of 19.40 thank you so much for the help and sticking with me.

    Calculating the Volume of a Mixture of Ethanol and Water

    ok I fixed it and I see I was dividing .931/18.05 instead of 18.05/.931 which would get me 19.40 thanks

    Calculating the Volume of a Mixture of Ethanol and Water

    Ok so here's how I set it up 8.04*.95/? +10 ok one last question though mass of the 95% solution I must divide is the total mass right so 18.04grams? If so I got this .42% the mass of this is .931 ok now for the final volume .931/18.04 and I got .051 aww like I was so close to the answer.

    Calculating the Volume of a Mixture of Ethanol and Water

    Thank you so much for the video I appreciate it so if my calculations come out correctly I should get 19.40 and then I can compare it to the 19.60 I actually measued

    Yes that is correct

    Calculating the Volume of a Mixture of Ethanol and Water

    hey I'm sorry I meant mass not volume when I wrote this "For ethanol it should have been 10ml* .804(because this is the density) and that should give me the volume?" ok so my mass calculated would be 8.04 grams for ethanol

    Calculating the Volume of a Mixture of Ethanol and Water

    Yeah I'm sorry guys this wasn't the main focus our our lab just a small section needed. Our main question for this section was why 10ml of ethanol+10ml of water added together doesn't add up to 20ml. I just needed these calculations for a table. I'm not sure if the 95% is mass or volume I just...

    Calculating the Volume of a Mixture of Ethanol and Water

    Yes I also think he wants us to calculate 20 ml and compare it to the 19.60 ml we measured the problem is my calculations just aren't adding up to 20ml.

    Calculating the Volume of a Mixture of Ethanol and Water

    Ok I think I see how I did my volume calculations wrong. For ethanol it should have been 10ml* .804(because this is the density) and that should give me the volume? or am I still on the wrong path haha. I think my volume calculation for water was right (10 * 1(density of water). So now my total...

    Calculating the Volume of a Mixture of Ethanol and Water

    So we did a lab where we mixed 10 ml of 95%ethanol with 10 ml of water and the volume of the mixture we measured was 19.60 ml. Even though we know the volume of the mixture is 19.60 our teacher wants us to calculate what the volume of the mixture should have really been and compare it to what we...
