Want this question answered?
the correct density numbers are the following water= 0.9982 g/mL Toluene= .8669 g/mL Clorofomo 1.4832 g/mL Ethanol= .789 g/mL
The mass will be 32.3 mL x 0.94 density = 30.362 grammes
270g
The question is not clear , if it is for the combustion of ethanol then 25litre of oxygen is in large excess for 25 ml of ethanol.
The density is 2,09 g/cm3.

In this case, you need to divide the volume by the density.
21ml x 1.74g/ml = 36.54 g
89.2g
If kgl is kg/L and gml is g/mL these densities are equal.
Density = Mass divided by Volume. 39.943 divided by 22.7 = about 1.76.
Depends on quantity. But assuming you have the same volume of both then Gold is definitely heavier.
yes
