First, the mixture of low-grade laterite nickel ore, coal, Na 2SO4 with a ratio of 100: 50: 17 was formed into pillow-like shape briquettes. Starch was used as a binder. The variations of Na2SO4 dose of as selective agent used in this research were 10% wt, 20 wt%, and 30 wt...
Finally, add together the total mass of each element to get the molar mass of Na2SO4(H2O)9: 45.97953856 g/mol + 32.065 g/mol + 207.9922 g/mol + 18.14292 g/mol = 304.17965856 g/mol 5. Find Mole Fraction To find the mole fraction and percentage of each element in Na2SO4(H2O)9,...
Find the percentage by mass of nitrogen present in (NH_4)_2SO_4. Calculate the formula mass and molar mass of NH_3. How many moles of NH3 would be formed from 50 grams of (NH4)2SO4 in the following equation? (NH4)2SO4 + 2NaOH = 2NH3 + 2H2O + Na2SO4 Calculate the molar ma...
True or False: \\ The percent composition of elements in a compound is determined from the compound's chemical formula by dividing the total mass of an element present in the formula by the molar mass of the compound. Percentage composition is ...
Finally, add together the total mass of each element to get the molar mass of Hg2O7SB2: 401.18 g/mol + 111.9958 g/mol + 32.065 g/mol + 21.622 g/mol = 566.8628 g/mol 5. Find Mole Fraction To find the mole fraction and percentage of each element in Hg2O7SB2, divide each total fr...
In the given problem, mass of the solute, mass of the solvent and volume of the solution is known. However, only information related to the masses are sufficient to compute the mass percentage of the components.Answer and Explanation:
The acidic peak, K0, K1 and K2 constitute approximately 13%, 60%, 10% and 8% of the intact MAb1, respectively, in terms of the integrated peak area percentage (Fig. 1). The CEX was used to fractionate MAb1 and generate milligram quanti- ties for each of the four charge variants. ...
