Math question!?!

OpenStudy (anonymous):

What is the weight (in grams) of a liquid that exactly fills a 465.0 milliliter container if the density of the liquid is 0.982grams over milliliter? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.

OpenStudy (anonymous):

@LarsEighner hello can you help?

OpenStudy (anonymous):

@mathmate hello can you help?

OpenStudy (mathmate):

There are some inconsistencies in the question...

OpenStudy (anonymous):

@mathmate how?

OpenStudy (mathmate):

"What is the \(weight\).." should read mass.

OpenStudy (larseighner):

There is no problem there. What do you think? You have one thing in ml and another thing in g/ml and you are asked for an an answer in g.

OpenStudy (anonymous):

@mathmate well thats exactly how i copied the question

OpenStudy (anonymous):

@LarsEighner so you get the gist of this question?

OpenStudy (mathmate):

That's ok. Just in case you're going on to physics.

OpenStudy (mathmate):

Tag me if @LarsEighner is no longer available.

OpenStudy (anonymous):

kk

OpenStudy (anonymous):

0.982grams/ 465.0 millilite

OpenStudy (anonymous):

@LarsEighner and so i dived them

OpenStudy (larseighner):

So the units grams divide by milliliters and you divided by milliters, so your answer is now in grams divided by milliliters divided by millilters. The question ask you for an amount in grams.

OpenStudy (anonymous):

so i did grams/mill and got 0.0021118

OpenStudy (anonymous):

@LarsEighner not sure what to do next

OpenStudy (larseighner):

The question said "0.982grams over milliliter" What do to it to get an answer in grams?

OpenStudy (anonymous):

Uhm i get 0.0021118 still confused

OpenStudy (larseighner):

If eggs are 1 dollars over dozen how much does 5 dozen cost?

OpenStudy (anonymous):

60

OpenStudy (larseighner):

I give up.

OpenStudy (anonymous):

@mathmate plz i just need the answer im so lost plus my wifi is die on me

OpenStudy (anonymous):

@ganeshie8

OpenStudy (anonymous):

idk divide it look the question up or something

OpenStudy (mathmate):

Use mass = volume * density as long as the quantities are in the proper units. Consistent units would be mass: grams, volume: mL or cc, density: g/ml or g/cc

OpenStudy (mathmate):

If this is a physics or chemistry question, you will need to give the answer to the appropriate accuracy. Volume was given to 4 significant digits, while the density was to 3 digits. So you answer could have a maximum of 3 significant digits.
