Use the de Broglie relationship between mass and wavelength (lambda).
lambda=h(Planck's constant)/[(mass)*(volume)]
lambda=6.626*10^-34/[(9.76*10^6)*(9.1094*10^-31)]
=7.45*10^-11 m
Answer:
Explanation:
Hello,
In this case, as the reaction between sodium hydroxide and sulfuric is:
We can notice a 2:1 molar ratio between the base and the acid, for that reason for the titration at the equivalence point we find:
Which in terms of concentrations and volumes is:
In such a way, solving for the required volume of base we find:
Best regards.
Answer:
A food chain shows how energy flows from one organism to another. In general, energy flows from the Sun to producers and then to consumers. The path is linear as the energy present in one step is transferred to the next. You can find specific examples of this pathway in an ecosystem
The volume in mL of ethanol (C₂H₆O) present in the bottle is 487.5L
HOW TO CALCULATE VOLUME OF ETHANOL:
- According to this question, a particular beer is 65.0% ethanol by volume. This means that the beer contains 65/100 of ethanol.
- If a single bottle of beer contains a total of 750.0 mL of beer, the volume of ethanol in the bottle is calculated as follows:
- Therefore, volume in mL of ethanol (C₂H₆O) present in the bottle is 487.5L
