How do you find the sample number?

How do you find the sample mean?

Add the values of the variable for all elements in the sample and divide by the number of elements on the sample.

How to find the mitotic index in a cell sample?

To find the mitotic index in a cell sample, count the number of cells undergoing mitosis and divide it by the total number of cells in the sample, then multiply by 100 to get the percentage. This helps determine the rate of cell division in the sample.

How can you get the molar mass of insulin knowing just the grams of insulin in a sample and the number of molecules that that sample contains?

To find the molar mass of insulin, you first need to calculate the number of moles of insulin in the sample using the Avogadro's number and the number of molecules. Then, divide the grams of insulin by the number of moles to find the molar mass. The molar mass is expressed in grams per mole.

How many moles of a substance with an atomic mass unit (amu) of 12 are present in a given sample?

To find the number of moles in a sample, divide the sample's mass by the substance's atomic mass unit (amu). For a substance with an amu of 12, the number of moles in the sample can be calculated by dividing the sample's mass by 12.

determine the subatomic particle ( electron, protons, neutron)?

For Example:- Calculate the number of protons, electrons, neutrons in Bromine with atomic number 35 and mass number 80. Hint: In order to answer this question you must recall the periodic properties and mole concept chapter in which you have done conversions regarding the number of moles, number of atoms, number of electrons, protons, and neutrons in a sample of given atomic number and mass number. Firstly, find the number of protons and the same number of electrons will be there and the sum of protons and neutrons form the mass number and you will get your answers. Complete step by step answer: Step 1: In this step we will find the number of protons of the given sample: Number of protons of a sample = Atomic Number of the element = 35 Step 2: In this step we will find the number of electrons of the given sample: Number of electrons of a sample = Number of protons = 35 Step 3: In this step we will find the number of neutrons of the given sample: Number of neutrons of a sample = (Mass number - Atomic Number) of the element Number of neutrons of a sample = 80 – 35 = 45 So, here we got our required values. The values are: No. of proton p = 35 No. of neutron n = 45 No. of electron e = 35 Note:The number of protons in the nucleus of the atom is equal to the atomic number (Z).The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

How many moles of a substance are present in a sample if the sample weighs 5 grams and the molar mass of the substance is 30 g/mol (Dalton to moles conversion)?

To find the number of moles in a sample, divide the sample's weight by the molar mass of the substance. In this case, if the sample weighs 5 grams and the molar mass is 30 g/mol, the number of moles present in the sample would be 0.167 moles.

What does it mean to find the range of the values?

take the largest number in the sample and subtract the smallest number that is the range

What will be the sample size?

Number of Sample in set of observation.

Where can you find a solution to problem solving number of moles in a given element?

Number of moles = Mass of the sample in g/Molar mass in g

Where can one find free sample consulting business plan templates online?

One can find free sample consulting business plan templates online from a number of websites. One can download them from 'BPlans', 'Smarta' and from 'Entrepreneur'.

What will happen if the sample you have drawn from the population does not represent the population?

You are studying the sample because you want to find out information about the whole population. If the sample you have drawn from the population does not represent the population, you will find out about the sample but will not find out about the population.

Is a sample a number describing some characteristic of a statistic?

No. A statistic is a number describing a characteristic of a sample.
