How will you prepare 270 ml of a 20% sucrose solution (w/v), given that sucrose has a molecular formula of C_{12}H_{22}O_{11}? You have 1 liter of a freshly prepared 0.1 M sucrose (molecular mass 342) solution, which means ___. a) 6.02\t...
White vinegar is a 5.0% by mass solution of acetic acid in water. If the density of white vinegar is 1.007 g/cm3, what is the pH? The ionization constant of lactic acid, CH3CH(OH)CO2H, an acid found in the blood after strenuous exercise, is 1.36 × 10−4. If 20.0 g of lactic...
A mass range of m=z 100–1000 was covered, and data were collected in the negative ion mode (ESI). i) L-FDAA derivatives of the common amino acids: the column was maintained at 40 C. CH3CN-H2O contain- ing 0.3% AcOH was used as the mobile phase with linear gradient elution (...
Using the simplest possible model, what is the relative size of the following two polymers of polystyrene as measured by the root mean square end-to-end distance? Number average molecular weight of the polymers: 1.10 kg/mol 2...
The relative stabilities of phases within the two systems monazite-(Ce) – fluorapatite – allanite-(Ce) and xenotime-(Y) – (Y,HREE)-rich f
In order to approach the factors controlling corrosion mechanisms of ZnMgAl in natural environments we have undertaken a series of studies in which the corrosion rates, mass balance, intrinsic reactivity, selective dissolution and corrosion products in different environments and exposure conditions were st...

The max relative deviation of the tip leakage mass flow was less than 0.13%. The convergence of the simulations was judged on residual histories, and the convergence criterion was 10−5. This convergence criterion ensured that the average numerical uncertainty of velocities was less than 0.1%. ...
