Which element Mo Se Na or Br contains the most moles of atoms in a 1.0 gram sample?
This element is sodium.
How many moles of specified particles are present in a sample of N'O if each sample weighs 7.00 g?
the mole is 30 g.
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.
What is the total number of moles present in a 52.0 gram sample of NaN3 gram formula mass equals 65.0 mole?
.8 moles
How many moles of silver (Ag) are present in a sample of 3.8 10 to the power of twenty four atoms Ag?
The answer is 6,31 moles Ag.
How many moles in 31.78G of Boron?
The atomic mass of B is 10.8Amount of B = mass of pure sample/molar mass = 31.78/10.8 = 2.94mol There are 2.94 moles of the element boron in a 31.78g pure sample.
How many moles of sulfur are present in a 16-g sample of sulfur?
No. of moles=given mass/gram molecular mass =16/16 =1
How many grams of carbon dioxide are present in a sample containing 80.0 moles of CO2?
80,0 moles of CO2is equal to 3 520,8 g.
Which element N S Pu or Cl contains the least moles of atoms in a 5.0g sample?
Number of moles = mass / molar mass, so the answer is the one with the greatest molar mass. This is plutonium.
When finding the moles of a gram sample of a diatomic element do you divide by twice the molar mass?
YE you do divide by 2
