What is the mean of 18 23 39 10 17 16 and 15?
sum = 138 sample size = 7 138 / 7 ~= 19.714285714285715
What is the mean of 18 23 39 10 22 17 16 15?
mean(18, 23, 39, 10, 22, 17, 16, 15) = (18 + 23 + 39 + 10 + 22 + 17 + 16 + 15) ÷ 8 = 160 ÷ 8 = 20
What is the mean of 23 12 15 25 10?
mean = the sum of the observed values / number of observations = 23+12+15+25+10 / 5 =85/5 =17

How many moles and how many atoms of zinc are in a sample weighing 34.9 g?
To find the number of moles of zinc, divide the sample's weight by the atomic weight of zinc (65.38 g/mol). This gives approximately 0.534 moles of zinc. To find the number of atoms, multiply the number of moles by Avogadro's number (6.022 x 10^23 atoms/mol) to get around 3.21 x 10^23 atoms in the sample.
How many Cu atoms are in the 0.0159 mol sample?
The molar mass of copper is approximately 63.5 g. To find how many of these are in our sample we must divide.0.0159/63.5 = 2.5 x 10 ^ -4 = 0.00025 moles. Each mole contains the Avogadro number of atoms, i.e. 6.023 x 10 ^ 23, so in total we have 0.00025x 6.023 x 10 ^ 23 = 1.51 x 10 ^ 20 atoms approximately.
How many molecules are in sample 57.45 CF2Cl2?
To calculate the number of molecules in a sample, you need to know the mass of the sample and the molar mass of the compound. Then you can use Avogadro's number (6.022 x 10^23) to convert from grams to molecules.
How many moles in a sample of 6.022x1023 molecules of colbalt chloride?
6.022*10^23 molecules of anything is one mole of that thing
The mass of argon is 6.63 x 10-24g How many atoms are there in a 40.0 g sample argon?
First, calculate the number of moles in the 40.0 g sample of argon: 40.0 g / 39.948 g/mol = 1.00 mol. Then, use Avogadro's constant (6.022 x 10^23 atoms/mol) to find the number of atoms in 1.00 mol of argon, which is 6.022 x 10^23 atoms.
How many moles are represented by 3.24x1023 atom sample of Ba?
3.24x10^23 barium atoms represent 0.537 moles, because 1 mole is equivalent to 6.022x10^23 atoms.
What is the mean of 18 23 39 10 22 17 16 15?
mean(18, 23, 39, 10, 22, 17, 16, 15) = (18 + 23 + 39 + 10 + 22 + 17 + 16 + 15) ÷ 8 = 160 ÷ 8 = 20
What is the mean of 23 12 15 25 10?
mean = the sum of the observed values / number of observations = 23+12+15+25+10 / 5 =85/5 =17
