In order to find the mass of sodium hydroxide required to make 200 cm3 of 2 M solution: 200 cm3 of a 2 M solution requires 21000× 200 moles. 0.4 moles of NaOH has a mass found by the equation: mass of NaOH = number of moles× relative molecular of NaOH mass of NaOH =0.4×(23...
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 lacti...
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]...

Simultaneously, the mass of each specimen was recorded using the scale with a resolution of 0.1 g. The specimens were stored in an air-conditioned laboratory with a temperature of (21 ± 2) °C and RH of (55 ± 10)% during the whole time of measurement....
