Help on these questions

Published

I am studying for a chemistry test can anyone demostrate the following question for me please...

1.Calculate the number of millimeters of water in a cubic foot of water.

2.Make the following conversions and include an equation for each one:

162 degrees farenheit to Celsius

0.0 F to K

-18 C to Farenheit

212 K to Celsius

3. One liter of homogenized whole milk has a mass of 1032 grams. What is the density of the milk in grams per milliliter? in Kilograms per liter?

Hi, dearluv20! I am moving this thread to the Student Assistance Forum, where you will be more likely to get the help you need! :)

1FT(3)=1728IN(30)/1FT(3) X16.3871CM(3)/1IN(3)x1ML/1CM(3)=

just multiply and divide across and cancel common units

*162f-32 X 5/9=

*0f -32c x 5/9 = answer--take that answer and plug into

(answer)c-273.15= answer in Kelvins

* 18c X 9/5 + 32 =F

*212K +273.15=C

sorry bout last one--not enough time, I am walking out of the office :) Hope it helped though

oops ...first line should read:

"1ft(3)=1728in(3)/1ft(3) x16.3871cm(3)/1in(3)x1ml/1cm(3)=

just multiply and divide across and cancel common units "

the 3's in parentheses are cubed signs--couldnt figure out the superscript thing

i created a paint file where i "hand wrote" the first problem and saved it as an image --it would probably help if you saw how i would write it as opposed to typing it..i can email it if you like

1.calculate the number of millimeters of water in a cubic foot of water.

you're on your own with this one. are you sure you copied the question correctly?

2.make the following conversions and include an equation for each one:

  • 162 degrees farenheit to celsius
  • 0.0 f to k
  • -18 c to farenheit
  • 212 k to celsius

you will find the formulas you need to convert these at this website:

however, here are the answers, so you can double check your calculations:

  • 162 f = 72.22 c
  • 0 f = 255.4 k
  • -18 c = -0.4 f
  • 212 k = -61.15 c

3. one liter of homogenized whole milk has a mass of 1032 grams. what is the density of the milk in grams per milliliter? in kilograms per liter?

density = mass / volumn

therefore, going from grams/liter to grams/milliliter

1032 grams
(mass)
/
l liter
(volumn)
x
1 liter
/
1000 ml (
conversion factor
)
=
1032 gram
/
1000 ml
which should be simplified to
1.032 gram/ml
(density)

going from grams/liter to kilograms per liter

1032 grams
(mass)
/
1 liter
(volumn)
x
1 kilogram
/
1000 grams (
conversion factor
)
=
1032kg
/
1000l
which should be simplified to
1.032kg/l
(density)

The first question is a typical problem that would be asked in Chemistry....they are all solved using Dimensional Analysis but the first one takes it one step further by converting from metric to standard measurements.
