How many grams of silicon would there be in a sample that contained 9.99 x 1025 atoms?
The mass of silicon is 4 659 g.
What is the number of atoms contained in 5.72 grams of glucose?
(5.72g c6h12o6)*6.022*10^23atoms c6h12o6/180.156gc6h12o6=1.91*10^22 atoms c6h12o6
How many atoms are in a 341g sample of scandium?
341 grams scandium (1 mole Sc/44.96 grams)(6.022 X 1023/1 mole Sc) = 4.57 X 1024 atoms of scandium =====================
How many LI atoms are contained in 97.9 of LI?
I assume you mean 97.9 grams lithium. 97.9 grams lithium (1 mole Li/6.941 grams)(6.022 X 10^23/1 mole Li) = 8.49 X 10^24 atoms of lithium ---------------------------------------
Which has the greatest number of atoms- 45 grams of Mg 45 grams of F 45 grams of P or 45 grams of Na?
In order to figure out how many atoms are in each sample, you would take 45, multiply it by 6.02 × 1023, and divided by the atomic mass. Since two of the numbers (45 and 6.02 × 1023) will be constants in all of the samples, the number of atoms will differ in each sample due to the atomic mass. 45 × (6.02 × 1023) / atomic mass in grams = number of atoms You could punch out all the numbers to see which sample has the greatest number of atoms, but it is easier to find the atomic mass for all of them and see which one is smaller. A larger atomic mass will mean the equation will be divided by a larger number, meaning the number of atoms will be smaller. So the smallest atomic mass would yield more atoms.Atomic masses:Mg- 24.3 grams***F- 38.0 gramsP- 31.0 gramsNa- 23.0 grams***Note that fluorine is a diatomic moleculeThe sample of 45 g of sodium (Na) would contain the greatest number of atoms
How many grams of silicon would there be in a sample that contained 9.99 x 1025 atoms?
The mass of silicon is 4 659 g.
How many atoms of silicon are contained in 8.5 x 10-5gm?
8.5 X 10^-5 grams silicon (1mol Si/28.09g)(6.022 X 10^23/1mol) = 1.8 X 10^18 atoms of silicon
How many grams of silicon would there be in a sample that contained 9.991052 atoms?
1 mol of Si contains 6.02 x 1023 atoms (avogadro constant). Amount of Si = (9.99x1052) / (6.02x1023) = 3.75mol Molecular mass of Si is 28.1. Mass of Si = 3.75 x 28.1 = 105g

There are 57.6 grams of tin in that sample.
How many atoms are contained in 131.1 grams of xenon gas?
Approx 6.01*10^23 atoms.

Approx 1.5*10^23 atoms.
How many grams would a sample of 3.01 x 1023 atoms of tellurium be?
63.8g
How many atoms are in sample of chromium with a mass of 13 grams?
Take the actual sample weight of 13grams, and divide it by the atomic weight of chromium. This gives you your molar percentage of atoms. Now multiply this molar percentage by Avogadro's constant, the number of atoms in one mole, and this will give you your number of atoms in the sample.
Thorium-234 has a half life of about 24 days of a sample that originally contained 100 grams of thorium-234 now only contains 25 grams.what is the age of the sample?
25 grams of Thorium-234
How many Si atoms in 12.5 g sample of silicon?
Silicon is a common metalloid which is a chemical element but it is considered to be tetravalent metalloid which has only 4 available electrons for covalent chemical bonding in its valence region. In the periodic table, Silicon has atomic number 14 with Si symbol. It is good to know that silicon is less reactive that Carbon-14 based on its position in the periodic table which is in the bottom of Carbon.The Standard Atomic Weight for Silicon is 28.0855 grams. The standard is based on the Avogadro's Constant which is 6.02214179 x 1023 mol-1. 1 mol of silicon will contains 6.02214179 x 1023 atoms of silicon. So, how many atoms are present in 12.5 gram of silicon?In 1 mol silicon (28.0855 grams) = 28.0855/28.0855 x 6.02214179 x 1023 = 6.02214179 x 1023 atomsIn 12.5 gram silicon = 12.5/28.0855 x 6.02214179 x 1023 = 2.680271755 x 1023 atomsRead more: How_many_silicon_atoms_are_there_in_1.00_g_of_silicon
What information does the molar mass gives?
It is the sum of the atomic weights of atoms contained in the molecule, expressed in grams.
