D. High Albedos is the correct answer
Answer:
2.9g/cm^3
Explanation:
We're given that the mass of the system before the rock was added was
120g
. The mass after the rock was added was 250g, so the rock's mass is 130g.
The initial volume of water in the graduated cylinder was
30
mL
, and the volume after the rock was added read 75mL
, so the rock's volume is 45mL
Density = Mass over Volume.
AKA. 130g/45mL
2.9g/cm^3 (rounded)
<u>Answer:</u> The solubility of B is high than the solubility of A.
<u>Explanation:</u>
The solubility is defined as the amount of substance dissolved in a given amount of solvent. More the solute gets dissolved, high will be the solubility and less the solute dissolved, low will be the solubility.
For the given observations:
Mass of undissolved substance of substance A is more than Substance B at every temperature. This implies that less amount of solute gets dissolved in the given amount of solvent.
Hence, substance B has high solubility than substance A.
