Divide both sides by p (rho). (vp= m is equal to v = m / p). The resulting value for v is the volume or three-dimensional size of the molecule. References WebQC: Calculate Molecular Weight – Molecular Mass Calculator The Chemical Heritage Foundation: Molecular Size Cite This Article M...
The science world is filled with different ways to express the vital concept ofconcentration, which is the amount of something present per unit volume. This "amount" often has units of mass but can include virtually anything that can be quantified: gas particles, photons and more. The volume ...
How many grams of sulfosalicylic (254g/mol) are required to prepare 1L of a 3% weight by volume solution? How to convert molecular weight from g/mol to lb/mol? Calculate the moles of Zn(NO3)2 in 143.50 g of this substance. Convert a mass of 6.16/lb to grams (2.2 pounds =1 kil...
How to calculate volume of NaOH required for titration How do you prepare the buret for titration? Why is HCl added for the titration of vitamin C? How do you calculate K_a from a titration curve? Calculate the pH of a 0.10 mol/L solution of ascorbic acid, H2C6H6O6(aq), and the...
I have asked two times the following question:I want to calculate the gas concentration, in ppm, in the closed chamber of volume 1025 cm3. I have a cylinder of mixture of NH3 and air with the 10 and 90% ratio respectively. we are flowing this gas mixture
As long as you have a way of measuring the mass of a solute, you can calculate its molarity by measuring the volume of the solution. Be careful here, because molarity is always expressed as moles/liter, so if you measure volume in any other units, you have to convert to liters. Here...

Calculate the amount of the component in moles using the formula, Amount (in moles) =mass (compound)/molecular mass (compound). In our example, Amount (NaOH)=0.5 g /40 g/mole= 0.0125 moles. Step 3 Convert moles to millimolesusing the following proportion: 1 mole corresponds to 1 milli...
Review how to calculate the mass of a liquid from its volume and density. Density is mass per unit volume: density = mass / volume You can rewrite the equation to solve for mass: mass = volume x density Densityof liquids usually is expressed in units of g/ml. If you know the density...
