What is the molar mass of haemocyanin and the freezing point of the solution when an aqueous solution is prepared by dissolving 1.5 grams of haemocyanin a protein obtained from crabs in 0.25 litres of?
Haemocyanins are a group of proteins.
What is the molarity of a 3.0 percent hydrogen peroxide H2O2 aqueous solution when the density is essentially 1.0g over mL?
If the density is 1.0 g/ml, one liter of the solution will weigh 1000 grams. 3.0 % of this mass or 30 grams of it is constituted of H2O2. The molar mass of H2O2 is 2 (1.008 + 15.999) = 34.014. The molarity of this solution is therefore 30/34.014 = 0.88, to the justified number of significant digits.
