Lithium Sulfate Li2SO4 has 4 oxygen atoms per molecule.
There are 4 atoms - three lithium (Li) atoms and one phosphorus (P) atom.
In 4 moles of magnesium hydroxide, Mg(OH)₂, there are a total of 20 atoms. Each formula unit of Mg(OH)₂ contains 1 magnesium atom, 2 oxygen atoms, and 2 hydrogen atoms, totaling 5 atoms per unit. Therefore, for 4 moles, you calculate 4 moles × 5 atoms/mole = 20 atoms.
To find the number of moles of H atoms in C2H4Cl2, we first need to calculate the molar mass of C2H4Cl2. The molar mass is 98.96 g/mol. Next, we calculate the moles of C2H4Cl2 in 47.2742 grams by dividing the mass by the molar mass which is 0.478 moles. Since there are 4 H atoms in one molecule of C2H4Cl2, multiply the moles of C2H4Cl2 by 4 to find moles of H atoms which is 1.913 moles.
To determine the number of atoms in 4 g of plutonium, you would first need to calculate the moles of plutonium in 4 g using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
To determine the number of moles of lithium in 20mL of 0.5mM lithium phosphate, first calculate the moles of lithium in 1mL of the solution: 0.5mM = 0.5 mmol/L = 0.5 × 10^-3 mol/L = 5 × 10^-4 mol/L Now, for 20mL: 5 × 10^-4 mol/L × 20 mL = 0.01 moles of lithium

Lithium Sulfate Li2SO4 has 4 oxygen atoms per molecule.
Lithium phosphate has the chemical formula Li3PO4, which means it contains 3 lithium atoms, 1 phosphorus atom, and 4 oxygen atoms. In total, there are 8 atoms in lithium phosphate.
Since 14 (4+10) moles of P4O10 contains 4 moles of Phosphorus, 8 moles of P4O10 will contain :: (8 x 4)/14 = 2.286 moles of Phosphorus
In Ca(HCO3)2, there are 2 moles of carbonate ions (CO3^2-), each containing 3 atoms. So there are 6 atoms in 1 molecule of Ca(HCO3)2. Therefore, in 4 moles of Ca(HCO3)2, there are 4 x 6 = 24 moles of atoms.
4 moles of oxygen atoms are present in 4 moles of H2O
There are 4 phosphorus atoms in one molecule of copper phosphate (Cu3(PO4)2). Therefore, in 7.6 moles of copper phosphate, there would be 7.6 moles x 4 atoms = 30.4 moles of phosphorus atoms.
There are 24 moles of hydrogen in 4 moles of CH4 because each molecule of CH4 contains 4 hydrogen atoms. Therefore, you have 24 moles x 6.022 x 10^23 atoms/mol = 1.4448 x 10^25 atoms of hydrogen.
0.4965 moles rounded to 4 significant figures
There are 4 atoms - three lithium (Li) atoms and one phosphorus (P) atom.
In a formula unit of lithium phosphate, the chemical formula is Li3PO4. This means there are 4 oxygen atoms present (1 phosphorus atom and 4 oxygen atoms).
