What is the mass of 3.91 x 1024 sulfur atoms?
To find the mass of 3.91 x 10^24 sulfur atoms, you can use the molar mass of sulfur (32.06 g/mol). First, find the number of moles by dividing the number of atoms by Avogadro's number (6.022 x 10^23). Then, multiply the number of moles by the molar mass to get the mass.
How do you find the number of neutrons in an elements atoms?
number of neutrons = mass number - atomic number
What is the mass of 1.63 x 1021 silicon atom?
To find the mass of 1.63 x 10^21 silicon atoms, you can start by calculating the molar mass of silicon (28.0855 g/mol). Then, divide the total number of atoms by Avogadro's number to find the number of moles (moles = atoms / Avogadro's number). Finally, multiply the number of moles by the molar mass to find the mass.
How many atoms of tin are in 119 g of tin?
To find the number of atoms, divide the given mass (119 g) by the molar mass of tin (118.71 g/mol) to get the number of moles. Then, multiply the number of moles by Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms.
How many copper atoms are in a pure copper statue with a mass of 148kg?
To find the number of copper atoms in the statue, you need to first determine the number of moles of copper using its molar mass. Then, you can multiply the number of moles by Avogadro's number to find the number of atoms. Given that the molar mass of copper is approximately 63.55 g/mol, you can follow these steps to calculate the number of copper atoms in the statue.
What mass of He contains the same number of atoms as 5.0 g Kr?
To find the mass of He containing the same number of atoms as 5.0 g Kr, we need to use the fact that atoms are indivisible entities. First, determine the number of atoms in 5.0 g Kr using the molar mass of Kr. Then, calculate the mass of He containing the same number of atoms by dividing the atomic mass of He by Avogadro's number and scaling it up to match the number of Kr atoms.
What is the mass in grams of 2x1012 atoms of potassium?
To calculate the mass of 2x10^12 atoms of potassium, you first need to find the molar mass of potassium (39.10 g/mol). Then, divide the number of atoms by Avogadro's number to get the moles of potassium. Finally, multiply the moles by the molar mass to find the mass in grams, which in this case would be 0.01566 grams.
How do you you work out the number of neutrons in an atom?
Atomic Mass minus atomic number
How do you find no of atoms if molar mass and density is given?
This is actually a chemistry question, but I found it in the math section... well anyways you use an equation with avogadro's number. P(density)=(((#atoms)(molar mass))/((avogadro's number)(volume))). You're solving for #atoms so rearrange the equation. You have density, molar mass, and avogadro's number. As for volume, assuming you know what element this is (which you should know from the molar mass even if it's not given), you should be able to compute volume from the unit cell measurements. If you do not know unit cells... I'm not sure.
How many atoms of oxygen are contained in 44g of CO2?
There are 1.5 x 10^23 atoms of oxygen in 44g of CO2. This can be calculated by converting the mass of CO2 to moles, using the molar mass to find the number of moles of oxygen, and then multiplying by Avogadro's number to find the number of atoms.
How many atoms are in 45 grams of pb?
To find the number of atoms in 45 grams of Pb (lead), we need to first calculate the number of moles. The molar mass of Pb is approximately 207.2 g/mol. By dividing the given mass by the molar mass, we can find the number of moles. Then, we can convert moles to atoms using Avogadro's number (6.022 x 10^23 atoms/mol).
How many atoms of nitrogen are in 20g of NH4NO3?
To find the number of atoms of nitrogen in 20g of NH4NO3, first calculate the molar mass of NH4NO3 (80.043 g/mol). Next, divide the mass of NH4NO3 by its molar mass to find the number of moles (0.2496 mol). Finally, multiply the number of moles by Avogadro's number (6.022 x 10^23) to determine the number of atoms of nitrogen (1.50 x 10^23 atoms).
