What tells you how many atoms an element has?
The atomic number of an element tells you how many protons an atom of that element contains. This number is unique to each element and is found on the periodic table. The number of protons in an atom determines the element's identity.
How many atoms are there in 1 mol of an element?
There are approximately 6.022 x 10^23 atoms in 1 mol of an element, which is known as Avogadro's number. This number is a constant and represents the number of atoms, ions, or molecules in one mole of a substance.
What can be said about 1 mol Ag and mol Au?
1 mol of Ag and 1 mol of Au can be said to contain the same amount of atoms of each element.
Does 23 g of sodium and 238 g of uranium have equal number of atoms in them?
No, the number of atoms in a substance is determined by Avogadro's number (6.022 x 10^23 atoms/mol). To calculate the number of atoms, you need to convert the mass of each element to moles first using their respective molar masses, which are 22.99 g/mol for sodium and 238.03 g/mol for uranium.
What is the molar mass of C4H8O4?
To determine the molar mass of a molecule, you need to determine the molar mass of each element from the periodic table, then multiply the molar mass by the subscript for the element in the formula. Do this for all of the elements in the formula and add them together to get the molar mass. The molar mass of an individual element is its atomic weight in grams. Molecular molar mass of C4H8O4 = (4 atoms C x 12.0107g/mol C) + (8 atoms H x 1.00794g/mol H) + (4 atoms O x 15.9994g/mol O) = 120.1039g/mol C4H8O4
What is the number of atoms in nitric acid with 0.093mol?
Each mol (of any substance) is 6.022*10+23 molecules, and each molecule HNO3 has 4 atoms, so you'll find the answer by multiplying these figures.The outcome will be (as correctly rounded estimate) 2.2*10+23 atoms in 0.093 mol HNO3
How many atoms are present in 80.0 mol of zirconium?
To determine the number of atoms in 80.0 mol of zirconium, you can use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Multiply 80.0 mol by Avogadro's number to find the total number of atoms in 80.0 mol of zirconium.
Are the number of atoms of bromine in 1 mol Br2 equal to avogadro's number?
No, the number of atoms in 1 mol of Br2 is equal to Avogadro's number multiplied by 2, because there are 2 atoms of bromine in each molecule of Br2. Avogadro's number represents the number of entities (atoms, molecules, etc.) in 1 mol of a substance.
What is the molar mass for tetraphosphorus trisulfide P4S3?
To determine the molar mass for any compound, you multiply the molar mass of each element (atomic mass in grams) times its subscript, which represents the number of atoms of that element. Then add the result for each element. Molar Mass of P4S3 (4 atoms x 30.974g/mol P) + (3 atoms x 32.06g/mol S) = 123.90g/mol P + 96.18g/mol S = 220.08g/mol P4S3
How many hydrogen atoms are in 0.1262 mol of H2SO4?
The formula shows that each mol contains 2 hydrogen atoms, and, for any substance, the number molecule per mole is Avogadro's Number. Therefore, 2 X 0.1262 X 6.022 X 1023 or about 1.520 X 1023 hydrogen atoms, to the justified number of significant digits.
How many atoms of phosphorus are in 8.90 mol of copperII phosphate?
To find the number of phosphorus atoms in 8.90 mol of copper(II) phosphate (Cu₃(PO₄)₂), we first identify that each formula unit contains 2 phosphorus (P) atoms. Thus, in 8.90 mol of copper(II) phosphate, the total number of phosphorus atoms is calculated as follows: 8.90 mol × 2 P/mol = 17.8 mol of phosphorus atoms. To convert moles to atoms, we multiply by Avogadro's number (approximately (6.022 \times 10^{23}) atoms/mol): 17.8 mol × (6.022 \times 10^{23}) atoms/mol ≈ (1.07 \times 10^{24}) phosphorus atoms.
Calculate molecullar weight of C10 H14 O8 Na2 N2.2H2 o?
The molecular weight of (C10H14O8Na2N2.2H2O) can be calculated by adding the molecular weights of each element in the compound. The molecular weight for each element is as follows: C=12.01 g/mol, H=1.01 g/mol, O=16.00 g/mol, Na=22.99 g/mol, N=14.01 g/mol, and H2O=18.02 g/mol. Calculate the total molecular weight by multiplying the number of atoms of each element by their respective atomic weight and summing them up.
