We are tasked to solve for the volume of Gold given that the mass of Gold is equivalent to that of a copper.
Details:
Density of Copper= 8.96 g/ml Volume of Copper=141 ml mass of Gold = mass of Copper Density of Gold=19.3 g/ml
In order to solve for the mass of copper, we need to use the density formula Density= mass/volume
Since we are to solve for the mass of copper mass of copper= Density of Copper * Volume of Copper mass of copper= 8.96 g/ml* 141 ml= 1263.36 g Thus, mass of gold=mass of copper=1263.36 g Hence, Using still the density formula to solve for the volume of gold, Volume of gold=mass of gold/ Density of gold Volume of gold=1263.36 g/ 19.3 g/ml = 65.46 mL
Therefore, the volume of the gold must be 65.46 mL in order to have the same mass of a copper
I got this stupid question wrong so that you people don't have to. I simply hate chemistry and I wish it didn't exist. Kind of like this website that makes me explain the answer.
The one from the cupboard because it is warmer (has more thermal energy) than the one from the refrigerator. When a liquid becomes warmer, the solubility of a gas becomes lower. Therefore, there is already more CO2 in its gaseous state when the soda is warm.
