What will happen when a pingpong ball is placed in a bucket of hot water?
The pingpong ball will float on the surface of the hot water due to buoyancy, as it is less dense than water. The ball may expand slightly due to the increase in temperature, but will not significantly alter its shape or weight.
Number-average molecular weight of a polypropylene is 1000000 gmol Compute the number-average degree of polymerization?
Number-average degree of polymerization = (Number-average molecular weight of polymer) / (Molecular weight of repeating unit) For polypropylene, the molecular weight of the repeating unit is 42 g/mol. Thus, degree of polymerization = 1000000 g/mol / 42 g/mol = 23809.52.
How many people would be equal to 8000 pounds?
What's the average weight of a person? 8000/average weight= number of people
What is an absolute weight?
An absolute weight is the weight of a specific number of things, such as seeds, in order to find the average weight of a single item.
Is the atomic number and the atomic weight the same?
No, the atomic number is the number of protons and electrons in a given element. The atomic weight is the weighted average of the isotopes in a natural environment.
What is the average molecular weight of the compound in question?
The average molecular weight of the compound is the sum of the atomic weights of all the atoms in the molecule, divided by the number of atoms.
What is the average weight of a school book?
The average weight of a school book is around 2-3 pounds. The weight can vary depending on the size, material, and number of pages of the book.
What is the average molecular weight of a polymer?
The average molecular weight of a polymer is the sum of the molecular weights of all the individual monomers that make up the polymer chain, divided by the number of monomer units. This average molecular weight can vary based on the length and arrangement of the polymer chain.
Which is the average of the mass number of an element isotpes?
The atomic weight or atomic mass.
How do you calculate number average molecular weight given molecular weight range and fraction?
To calculate the number average molecular weight, multiply each molecular weight value within the range by its corresponding fraction, then sum up these products. This sum represents the numerator of the equation. Next, sum up all the fractions in the denominator. Finally, divide the numerator by the denominator to obtain the number average molecular weight.
What is the average weight of a 8th grade girl?
Weight varies with height. Age and sex don't target any number.
Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.
