How many atom are in 0.670 grams of P2O5?
To find the number of atoms in 0.670 grams of P2O5, first calculate the molar mass of P2O5, which is approximately 283.88 g/mol. Next, determine the number of moles in 0.670 grams by dividing the mass by the molar mass: 0.670 g / 283.88 g/mol ≈ 0.00236 moles. Since each molecule of P2O5 contains 7 atoms (2 phosphorus and 5 oxygen), multiply the number of moles by Avogadro's number (approximately (6.022 \times 10^{23}) molecules/mol) and then by 7 to find the total number of atoms: 0.00236 moles × (6.022 \times 10^{23}) molecules/mol × 7 ≈ 9.86 × (10^{20}) atoms.

Moles of H2SO4 in 20 ml of 4M solution?
To find the moles of H2SO4 in a 20 ml of 4M solution, use the formula: Moles = Molarity x Volume (in liters). First, convert 20 ml to liters (20 ml = 0.02 L). Then, multiply the molarity (4 mol/L) by the volume (0.02 L) to find the moles of H2SO4, which is 0.08 moles.
How many moles are present in a sample of H2SO4 with a mass of 9.8g?
To find the number of moles in the sample of H2SO4, we need to divide the given mass by its molar mass. The molar mass of sulfuric acid (H2SO4) is 98.08 g/mol. Therefore, 9.8g / 98.08 g/mol = 0.1 moles of H2SO4.
total number of atoms and molecules in 5H2SO4?
To determine the total number of atoms and molecules in 5H2SO4, we first need to break down the chemical formula of sulfuric acid (H2SO4): 1 molecule of H2SO4 contains: 2 atoms of hydrogen (H) 1 atom of sulfur (S) 4 atoms of oxygen (O) Therefore, in 5 molecules of H2SO4, we have: 5 x 2 atoms of hydrogen = 10 hydrogen atoms 5 x 1 atom of sulfur = 5 sulfur atoms 5 x 4 atoms of oxygen = 20 oxygen atoms So, in total, there are 10 hydrogen atoms, 5 sulfur atoms, and 20 oxygen atoms in 5 molecules of H2SO4. Additionally, to find the total number of molecules in 5H2SO4, we simply multiply the coefficient (5) by the number of molecules in the formula (1 H2SO4 molecule) to get: 5 x 1 = 5 molecules of H2SO4. Therefore, in 5H2SO4, there are: 10 hydrogen atoms 5 sulfur atoms 20 oxygen atoms 5 molecules of H2SO4.
How many moles of H2SO4 are in 20 ml of 4 M solution?
To find the number of moles of H2SO4 in 20 ml of 4 M solution, we first need to calculate the number of moles present in 20 ml of the solution using the formula: moles = Molarity x Volume (L). Converting 20 ml to liters (20 ml = 0.02 L) and then calculating moles: 4 M x 0.02 L = 0.08 moles of H2SO4.
How many atoms in 179g of calcium?
To find the number of calcium atoms in 179g of calcium, first calculate the molar mass of calcium which is approximately 40.08 g/mol. Next, divide the given mass by the molar mass to get the number of moles (179g / 40.08 g/mol ≈ 4.47 moles). Finally, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms (4.47 moles * 6.022 x 10^23 atoms/mol ≈ 2.69 x 10^24 atoms). Therefore, there are approximately 2.69 x 10^24 atoms in 179g of calcium.
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.
What is mass in grams of 1x10 power 20 atoms of NA?
1mol Na in grams = 22.989770g 1mol Na atoms = 6.022 x 1023 atoms 1 x 1020 atoms Na x 1mol/6.022 x 1023 atoms x 22.989770g/mol = 0.004g Na (rounded to one significant figure)
A sample of gold has a mass of 5.00 x 10-3g. what amount of gold in atoms does the sample contain?
To determine the number of gold atoms in the sample, you can use the molar mass of gold (197 g/mol) to first find moles, then convert moles to atoms using Avogadro's number (6.022 x 10^23 atoms/mol). First, find moles: 5.00 x 10^-3 g ÷ 197 g/mol = 2.54 x 10^-5 mol. Then, convert moles to atoms: 2.54 x 10^-5 mol x 6.022 x 10^23 atoms/mol = 1.53 x 10^19 atoms.
How many grams do 3.61020 atoms of silicon weigh?
Each mole of particles have 6.02 x 10^23 particles. (3.6 x 10^20) / (6.02 x 10^23) = 0.000598 mol of Silicon Ar of Si (Silicon) = 28.1g/mol mass = number of moles x Ar mass = 0.000598 mol x 28.1g/mol = 0.0168g of silicon
If you start with 20 grams of hydrochloric acid how many grams of sulfuric acid will be produced?
Non!!!! They are two different substances/acids. The formulas for sulphuric acid is H2SO4 and for hydrochloric acid (HCl). With the exception of the hydrogens all the other elements present in the two difference acids are different.
How many moles of carbon atoms are there in 3 grams of carbon?
The questions asks how many moles of carbon atoms.Molar mass is defined as the mass of one mole of a substance or in this case 6.022x1023 atoms of carbon. So the molar mass for carbon is 12.0 g/mol. Therefore the number of moles of carbon atoms is just 36/12.0 = 3.0 moles of carbon.How many atoms are in 36 grams of Carbon?[36 (gC) /12.0 (gC/molC)] * 6.02*10+23 (atoms C/molC) = 1.8*10+24 atoms in 36 g Carbon
