Calculate Mass of 1L Ice @ -2°C: Density x Volume x Temperature

[Isho]

Homework Statement

If the density of ice at -2 Degrees Celsius is 0.917 g cm to the power of negative cubed (-3), what would be the mass of 1 litre of ice at this temperature ?

Homework Equations

None ? I'm guessing H = M x C x T though?

The Attempt at a Solution

I cannot attempt it. I was absent when My class did it so I have no idea how to do it. Can someone maybe explain to me how?

Much appreciated! Thanks.


P.S. I'm new here :). As I'm nearing my completion of High School (1 year and 1 month to go) I'll be more active in forums like these. Hi!

What is definition of density? What is a litre? How is it related to 1 mL? To 1 cm³?

Hello and welcome!

To calculate the mass of 1L of ice at -2°C, we can use the formula Density x Volume x Temperature.

First, we need to convert the temperature to Kelvin by adding 273.15 (0°C = 273.15K, -2°C = 271.15K). This is important because temperature must be in Kelvin for this equation to work.

Next, we need to convert the volume from liters to cubic centimeters (cm^3) because the density given is in grams per cubic centimeter. 1L = 1000cm^3.

Now we can plug in the values into the formula:

Mass = 0.917 g/cm^3 x 1000 cm^3 x 271.15K

Simplifying, we get:

Mass = 0.917 x 1000 x 271.15 g

Mass = 248.945 g

Therefore, the mass of 1L of ice at -2°C is approximately 248.945 g.

I hope this helps! Let me know if you have any further questions. Good luck with your studies!
