D= M/V so, D=300/40 wich is 7.5 so D= 7.5g/m3
Pure sugar can be obtained from sugar solution by the process of crystallization. It involves heating which leads to evaporation of water to make the solution saturated. The saturated solution when left undisturbed convert to pure crystals of the sugar.
B
When frequency increases, as does the energy, but wavelength decreases. It also works vise versa; if wavelength were to increase, its frequency and energy will decrease.
I think its C: due to mixing and oceanic.....
On complete conversion (100% yield) 9.75 g of ethyl butyrate will be produced. Below is the solution.....
