In order to find the mass of sodium hydroxide required to make 200 cm3of 2 M solution: 200 cm3of a 2 M solution requires21000× 200 moles. 0.4 moles of NaOH has a mass found by the equation: mass of NaOH=number
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...
The mass spectrometer was operated in dynamic Multiple Reaction Monitoring (dMRM) mode with the detector set to negative ion mode. Analyte acquisition parameters are detailed in Table S3. Data analysis was performed using MassHunter Qualitative Analysis Navigator (Version B.08.00, Build 8.0.8208.0),...
9. A process as claimed in claim 8 wherein the crosslinking agent is a zirconium lactate of formula [CH3CH(OH)CO2]nXmZr where X is a halide or hydroxide, m and n are integers such that m+n=4 and n is 1 to 4. 10. A process as claimed in claim 1 wherein the concentration of...
The oil phase may include at least one co-solvent. In particular, the co-solvent is used when the mass of tetraconazole present in the liquid agrochemical mixture is not sufficient to dissolve or disperse the one or more additional active ingredients present. ...

The corrosion products can modify mass and charge transport to/from the surface, limiting corrosion rate. The inhibiting effect of several patinas, either synthetic or formed during field exposure, on the electrochemical reactivity of the Zn-based coatings has been demonstrated by many authors [1]...
C is the maximum number/mass of devices used per patient D is the dilution or concentration factor UF is an uncertainty factor applied to account for RF variation and has previously been defined as UF = 1/(1-RSD) where RSD is the relative standard deviation of a response factor database....
