How many atoms are in 0.455 moles of lead?
Atomic mass: 207.2 grams.455 moles × (6.02 × 1023) = 2.74 × 1023 atoms of lead
How many grams are there in 7.97 x 10 to the 24 power atoms of calcium?
To calculate the grams in 7.97 x 10^24 atoms of calcium, you need to divide the number of atoms by Avogadro's number (6.022 x 10^23). Then multiply this result by the molar mass of calcium (40.08 g/mol). This calculation would give you the weight in grams of 7.97 x 10^24 atoms of calcium.
How many moles are in 2.16 10 to the 24 power atoms of lead?
To find the number of moles in 2.16 x 10^24 atoms of lead, you would divide the number of atoms by Avogadro's number, which is 6.022 x 10^23 atoms/mol. Thus, 2.16 x 10^24 atoms of lead is equal to 3.59 moles.
7.5 times 10 to the 21 uranium atoms equals how many grams?
To convert uranium atoms to grams, you need to know the molar mass of uranium. Uranium's molar mass is approximately 238.03 g/mol. Therefore, 7.5 x 10^21 uranium atoms would weigh approximately 0.625 grams.
How many atoms does 100 grams of gold have?
To find the number of atoms in 100 grams of gold, you would first calculate the number of moles using the molar mass of gold (197 grams/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. So, approximately 3.01 x 10^23 atoms of gold are present in 100 grams.
What is the mass of 6.25x1020 atoms of lead?
The molar mass of lead (Pb) is 207.2 g/mol. To find the mass of 6.25x10^20 atoms, you need to divide the number of atoms by Avogadro's number (6.022x10^23) to get the number of moles, then multiply by the molar mass of lead. The mass of 6.25x10^20 atoms of lead is approximately 1.72 grams.
How many grams of lead is needed to equal the number of atoms contained in 10 grams of tin?
Let us do this in two parts for clarity. Find atoms in tin first. 10 grams tin (1 mole Sn/118.7 grams)(6.022 X 1023/1 mole Sn) = 5.07 X 1022 atoms of tin ----------------------------------- 5.07 X 1022 atoms (1 mole Pb/6.022 X 1023)(207.2 grams/1 mole Pb) = 17 grams of lead ------------------------------ I can see two other ways to do the conversion string, one longer and one much shorter. See if you can find them.
How many atoms are there in 80 grams of lead?
To calculate the number of atoms in 80 grams of lead, you first need to determine the number of moles of lead using its molar mass (207.2 g/mol). Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms. So, for lead, there are approximately 3.86 x 10^23 atoms in 80 grams.
What is the mass of lead?
Lead (Pb) has the atomic number 82 with an Atomic Mass of 207.2 amu.
How many atoms are in 0.455 moles of lead?
Atomic mass: 207.2 grams.455 moles × (6.02 × 1023) = 2.74 × 1023 atoms of lead
How many argon atoms are contained in 10 grams of argon gas?
Approx 1.5*10^23 atoms.
How many atoms are in 21.84 grams of C?
There are approximately 3.633 x 10^23 carbon atoms in 21.84 grams of carbon.
What is the mass in grams of 1.00 X 1012 lead (Pb) atoms?
To find the mass of 1.00 x 10^12 lead atoms, you would first determine the molar mass of lead (Pb), which is 207.2 g/mol. Then, divide the total number of atoms by Avogadro's number to get the number of moles, and finally multiply by the molar mass to get the mass. So, the mass of 1.00 x 10^12 lead atoms is approximately 3.14 x 10^-9 grams.
