Question

Suppose you have 2.50 L of a substance with a density of 3.00 g/mL. Convert the volume from liters to milliliters, then determine the mass of the sample in grams and convert ot kilograms.

I appreciate any help! Thank you

Answer 1

We know, mass = density * volume
Here, density = 3 g/mL
volume = 2.50 L = 2500 mL

Substitute their values,
m = 3 * 2500
m = 7500 g

In short, Your Answer would be 7500 Gram

Hope this helps!

Answer 2

Answer : The mass of sample is 7.5 kilograms

Explanation :

Density : It is defined as the mass contained per unit volume.

Formula used :

`Density=(Mass)/(Volume)`

Given :

Density = 3.00 g/mL

Volume = 2.50 L = 2500 mL

conversion used : (1 L = 1000 mL)

Now put all the given values in the above formula, we get:

`3.00g/mL=(Mass)/(2500mL)`

`Mass=7500g=7.5kg`

conversion used : (1 kg = 1000 g)

Therefore, the mass of sample is 7.5 kilograms
