Density Practice Problems

This chemistry video tutorial explains how to solve density problems. It provides all of the formulas and equations you need such as finding the volume of a sphere or the volume of a rectangular prism. It even covers dimensional analysis and unit conversion density problems where you may have to convert g/mL to Kg/m^3. This video contains plenty of examples and practice problems including water displacement method density problems.

For problem #2, 3950g is correct, however the question was asking for it in kg. The proper dimensional analysis conversion is to take the 3950g, and multiply it by (1g/10^3kg)=3.95kg. If you look at the metric unit factor amount of kilo, you will see that kilo means 10^3. So you grab the initial amount, multiply it by 1g to cancel out the grams in the initial amount, then divide it by kilo 10^3 which amounts to 3.95kg. I hope this helps!

since I'm basically relearning all this with your help...I'll watch through your ads..

You’re honestly the best person ever. You’ve helped me throughout my college YEARS. I feel like I owe you, literally. You helped me so much and I couldn’t have done it without you

[robinlaunsby]

In your answer to #2 you give it in grams, however, your question states kilograms

"you have an iron bar with height x 4 width x 2 length x 3 what does that give u?"
me:an iron dagger(skyrim lvl up sound)

You are helping me so much to pass my chemistry final exam. I will donate as soon as I can. Thank you!

[devilsob]

thank you for the tutorial! my math teacher doesn't know how to use teams that well so I'm glad I can always come here when I don't understand :-)

[nyla_roohi]

I really understand how to solve my school problems with this channel. it is one of my favourite youtube channels.

[janellep]

Forget about the video, I love your voice ! so soothing .

Is it possible to find the height of a cylinder only given the density and radius? I wasn't provided the mass in my problem and I have no idea what to do

[georgesadler]

Professor Organic Chemistry Tutor, thank you for a solid analysis of Density Practice Problems in AP/General Chemistry. The practice problems/examples really show how to calculate Density using the given formula. Thanks to viewers for finding and correcting the small error in problem number two. The final solution to problem number two should be in terms of Kilograms not Grams.

Thanks so much for this video. You've shown all kinds of problems, which was really useful.

I am learning with you sir really good your voice is clear and easy to understand thank you so much for this video.

Fuel tank holds 22.3 gallons of gasoline. Density of gasoline is 0.8206 g/mL, what is the mass in kg of gasoline in a full tank?
(I can’t seem to figure it out. We are looking for mass, so multiple D and V to get 18.298380 mL and I divided by 1000 mL since 1 kg = 1000 mL, so I got 0.0183 kg as I rounded)


I have a problem I’m stuck on. I’ve watched your videos, but when I try to do it myself, I can’t seem to get the right answer!

[MeliStephanie]

What is the program that you used to do that video?

[kschannel]

Finally I've found a very detailed explanation! Thank you so much Sir! 😊😊😊

[darinstarks]

Math is like that. Multiple steps can make you forget a step. This is the only site I like to use for anything having to do with mathematics.

[davetoth]

Your videos are really well done. Thanks so much.

What is the density (in g/L) of a gas with a mass of 60 g/mol at 0.75 atm and 27 ⁰C?
Help🥲🥲🥲

[quickfood]

if you have a mass of granite 15.6g "suspended" can a mass of 5.5g of water displacement finding the density
