the molarity of a 0.6 moles of NaCl dissolved in 0.45 liters is 1.33 M (0.6 mol ÷ 0.45 L). Do this for both substances to let you calculate the final concentration of the solution. (Remember
(a) Determine the unit cell volume (b) Calculate the density of T_{i} Integration provides a mean to compute how much mass enters or leaves a reactor over a specified time period as in Calculate the value of the diffusivity, D, in meters squared per se...
But how is it possible to achieve these different results? In a previous article, we already showed how to calculate the correct light intensity required for each environment. Here, we compile a list of some of the key types of lighting systems. Save this article Read more »...
Hazard and risk assessment of nanomaterials (NMs) face challenges due to, among others, the numerous existing nanoforms, discordant data and conflicting results found in the literature, and specific challenges in the application of strategies such as grouping and read-across, emphasizing the need for...
Titration is a process for finding the concentration of a chemical solution. Titration makes use of the physical evidence of a chemical reaction to determine the amount of a known chemical that is required to completely react with the unknown chemical. This can then be used to calculate how muc...
Calculate the minute respiratory volume of an individual who has a tidal volume of 500 mL and a respiratory rate of 12 breaths per minute. How do breath-holding and moderate exercise affect the R-R interval, P-R interval and Q-T interval (ECG) compared to rest? How will an ECG change...
chronic stress, chronic inflammation and many chronic diseases. As previously discussed,Reverse T3 binds to Thyroid hormone receptors but does not have the beneficial effect of normal T3,thus blocking T3 from doing its job. Most physiciansdo not measure reverse T3 or calculate the T3/reverse T3 ...
The DNV RP-C203 like all direct fatigue damage rule-based codes as Eurocode 3, BS 5400, IIW-1823-07 use S-N curves to calculate direct fatigue damage. Allowable stress design codes as the EN13001, FEM 1.001, DIN15018, NEN 2018, NEN 2019, EN280, etc. use these curves as well but ...
In cellular biology the membrane potential describes the concentration of ions on each side of a membrane. The Goldman Equation includes other factors like the permeability of the cell membrane and the type of transfer across the surface to calculate this potential. When these cells reach equilibrium...
The detected intensities from the mass spectrometer were calibrated by linear regression, and then the equation of the calibration curve was used to calculate concentrations of dissolved ions in the electrolyte. The dissolution rate of Al is converted by subtracting the solute contribution from the ...
