• Speed and Mass Ratios

  (speed / speed of light ) and mass ratios (mass / mass at rest ) of electrons and protons.

• Find molar composition from percent by mass

  Comparing masses of substances is not how a chemist works, a chemist must compare mole ratios, not mass ratios.

• Determine salt mixture compostition of substance based on limiting reactant

  I must assume you have the mass of the known reactant in the data you have available as well as its identity. The mass of the precipitate is known.

• A sample of unknown Y is subjected to elemental analysis

  Chemical formulas are simply mole ratios, and what we have above is mass ratios....we need moles of each not mass of each....

• Mass to charge ratio

  ., x^a * x^b = x^(a+b) Therefore, (10^-19)*(10^-12) = 10^(-19-12) = 10^-31 This calculates the mass to charge ratio and mass of an electron. The mass to charge ratios are determined.

  Chemical Engineering: Using real data from large scale reactor processes to extract key data such as conersion, yield, selectivity and erquired molar ratios.

• Ratios for financial statement analysis - limitations

  Ratios may be misleading because of a one-time event (such as a large customer default, special inventory purchase, large sale throwing off cash right at year end, and so forth).

• Calculating mass and thickness

  In this case: The mass is the density r multiplied by the volume V or M=V*r in our case: r=1.06*10^3 kg/m^3 V=1pt M=Vr=[1.06*10^3 kg/m^3]*[1pt] To convert to grams we use the conversion ratios: 1m=100cm 1m^3=10^6 cm^3 [1m^3 /
