How do you calculate the weight of a solid object?
Find the volume of the sample (Length times width times height) and multipy by the density coefficient.
How do you convert 32 mmol in to grams?
1) Convert to moles. I assume mmol means minimole, so you divide by 1000. 2) Multiply the number of moles by the atomic or molecular weight. The molecular weight is different for different substances; you'll have to look it up or calculate it.
Why you need sampling distribution?
in order to calculate the mean of the sample's mean and also to calculate the standard deviation of the sample's
How do you calculate mineral contents of the sample?
We would need to know what sample you are referring to in order to answer this question.
How do you calculate sample size?
Count up the number of obseravtions made on the experimental units. That is the sample size.
What is the weight average molecular weight of the compound in question?
The weight average molecular weight of the compound is the average of the molecular weights of all the molecules in the sample, weighted by their relative abundance.
How many molecules are contained in a 4.75-g sample of dimethylmercury?
To calculate the number of molecules in a sample, you need to know the molecular weight of the substance. The molecular weight of dimethylmercury is approximately 214.77 g/mol. Using this information, you can determine the number of moles in the 4.75-g sample and then convert that to the number of molecules using Avogadro's number.
What is the weight average molecular weight of the polymer in question?
The weight average molecular weight of the polymer is the average of the molecular weights of all the polymer chains in the sample, taking into account the weight of each chain.
What is the method to calculate the mass in grams of each sample?
To calculate the mass in grams of each sample, you can use a balance or scale to measure the weight of the sample. The weight measured in grams is equivalent to the mass of the sample.
Why do you need a molecular weight ruler alongside your samples during electrophoresis?
A molecular weight ruler is used during electrophoresis to estimate the size of the DNA or protein fragments being separated in the gel. By comparing the migration of the sample bands to the known molecular weight markers, scientists can determine the approximate size of their samples.
What is the process to calculate the gram molecular weight of the unknown liquid?
To calculate the gram molecular weight of an unknown liquid, you need to determine the molecular formula of the liquid and then add up the atomic weights of all the atoms in the formula. This will give you the gram molecular weight of the unknown liquid.
How to calculate empirial formula from molecular formula?
To calculate the empirical formula from a molecular formula, divide the subscripts in the molecular formula by the greatest common factor to get the simplest ratio of atoms. This simplest ratio represents the empirical formula.
How do you calculate equivalent weight of oxide?
To calculate the equivalent weight of an oxide, you first determine its molecular weight. Then you look at how many oxygen atoms are present in the formula of the oxide and divide the molecular weight by that number of oxygen atoms. This result is the equivalent weight of the oxide.
How many lb-moles of substance are present in the given sample?
To determine the number of lb-moles in a sample, divide the weight of the sample in pounds by the molecular weight of the substance. This will give you the number of lb-moles present in the sample.
Is molecular weight an intensive or extensive property?
Molecular weight is an extensive property because it depends on the amount of substance present. It increases proportionally with the quantity of molecules in the sample.
How many moles in NaCHO3?
A mole is a defined number of atoms/molecules of an element/compound. Therefore, the number of moles of NaCHO3 will depend on the mass of NaCHO3 that you have. To calculate the number of moles in a known sample, divide the mass of the sample (in grams) by the molecular weight.
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.
