Want this question answered?
Density is 1.6 g/mL
50 grams
1.6 g/ml
density = mass/volume = 100g/50mL = 2g/mL
If water froze (ice), then it would be less dense than the water itself.
This question cannot be answered unless you know the density of the substance that you are asking about. For example, water has a density of 1 gram per mL of liquid, so there would be 125 grams of water in a 125 mL volume of water. For another other substance, the answer will vary depending on its density.
The density is the same.
4.03 g/cm^3
Only if the density or concentration is 1 mg/ml
Density is 1.6 g/mL
50 grams
You can weigh it; or you can calculate it based on the known density of water.
1.6 g/ml
The density of 40ml of saline solution in a 50 ml beaker is 1.0046g/mL. The density will vary based upon the concentration of the salt added to the solution.
I'll use the density of water here, ~ 1 g/ml. 125mg is 0.125g. This is 0.125 millilitres.
Density = mass/volume = 43.5/50 = 0.87 grams per ml.
Density = Mass/Volume ... in this case:50 gm/10 ml = 5 gm/ml
