How many C atoms are present in the sample of C3H8 with mass 5.31 g?
To find the number of carbon atoms in a sample of C₃H₈ (propane) with a mass of 5.31 g, first calculate the molar mass of C₃H₈, which is approximately 44.1 g/mol (3 carbon atoms × 12.01 g/mol + 8 hydrogen atoms × 1.01 g/mol). The number of moles of C₃H₈ in 5.31 g is about 0.120 mol. Since each molecule of C₃H₈ contains 3 carbon atoms, the number of carbon atoms is 0.120 mol × 3 × Avogadro's number (approximately 6.022 × 10²³), which equals about 2.17 × 10²³ carbon atoms.
How many atoms are in 1.8 g C?
To find the number of atoms in 1.8 grams of carbon (C), first calculate the number of moles of carbon using its molar mass, which is approximately 12.01 g/mol. Dividing 1.8 g by 12.01 g/mol gives about 0.15 moles of carbon. Since one mole contains approximately (6.022 \times 10^{23}) atoms (Avogadro's number), multiplying 0.15 moles by (6.022 \times 10^{23}) atoms/mole results in approximately (9.02 \times 10^{22}) atoms of carbon.

5 g of sulfur contain 0,94.10e23 atoms.
What statement about krypton is not true A its molar mass is 83.798 g per mol Kr B Its atomic number is 36 C one mole of krypton atoms has a mass of 41 point 90g D it is a noble gas?
Statement C is not true. One mole of krypton atoms has a mass of approximately 83.798 g, not 41.90 g.
How many Atoms are in 169g of c?
169 g C x 1 mole C/12.011 g x 6.02x10^23 atoms/mole = 8.47x10^24 atoms
How many carbon atoms are contained in 85.9 g of carbon?
85.9 (g C) = 85.9 (g C) / 12.00 (g/mol C) = 7.158 (mol C)7.158 (mol C)*[6.022*1023 (atoms/mol C)] = 4.31*1024 C-atoms
How many atoms are in a 12 g of C?
To find the number of carbon atoms in 12 g of carbon (C), you first need to calculate the number of moles of carbon (C) in 12 g using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23) to determine the number of atoms in that many moles of carbon (C).
How many C atoms are present in the sample of C3H8 with mass 5.31 g?
To find the number of carbon atoms in a sample of C₃H₈ (propane) with a mass of 5.31 g, first calculate the molar mass of C₃H₈, which is approximately 44.1 g/mol (3 carbon atoms × 12.01 g/mol + 8 hydrogen atoms × 1.01 g/mol). The number of moles of C₃H₈ in 5.31 g is about 0.120 mol.

How many atoms are in 1.6 g C?
There are approximately 1.34 x 10^22 carbon atoms in 1.6 g of carbon. This calculation is based on the molar mass of carbon (12 g/mol) and Avogadro's number (6.022 x 10^23 atoms/mol). To find the number of atoms, divide the mass of the sample by the molar mass of carbon, and then multiply by Avogadro's number.
How many atoms are in 49.1740 g of zirconium?
49.1740 g (6.02 x 1023 atoms) / (91.22 g) = 3.25 x 1023 atoms
How many moles of atoms are contained in 5.21x10E24 C2H2?
To find the number of moles of atoms in a compound, first calculate the molar mass of the compound (12 g/mol for carbon, 1 g/mol for hydrogen). Then divide the given number of atoms by Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of moles. In this case, 5.21x10^24 atoms of C2H2 would be equivalent to approximately 8.65 moles.
How many atoms of carbon c are in 0.09 g of carbon?
divide by the atomic mass and times it by advogadro's number.
How many atoms of carbon are in a pure sample of carbon having a mass of 72.0 g?
There are 6.022 x 10^23 atoms in 1 mole of carbon. The molar mass of carbon is 12 g/mol. Therefore, in 72.0 g of carbon, there are (72.0 g / 12 g/mol) * 6.022 x 10^23 atoms = 3.61 x 10^24 atoms of carbon.
How many atoms of carbon (C) are in 0.08 g of carbon?
To find the number of carbon atoms in 0.08 g of carbon, you need to calculate using Avogadro's number and the molar mass of carbon. The molar mass of carbon is approximately 12 g/mol. First, convert grams to moles by dividing 0.08 g by the molar mass of carbon to get approximately 0.0067 moles of carbon. Then, multiply the number of moles by Avogadro's number (6.022 x 10^23) to find that there are approximately 4 x 10^21 atoms of carbon in 0.08 g.
How many atoms are in 1.8 g C?
To find the number of atoms in 1.8 grams of carbon (C), first calculate the number of moles of carbon using its molar mass, which is approximately 12.01 g/mol. Dividing 1.8 g by 12.01 g/mol gives about 0.15 moles of carbon. Since one mole contains approximately (6.022 \times 10^{23}) atoms (Avogadro's number), multiplying 0.15 moles by (6.022 \times 10^{23}) atoms/mole results in approximately (9.02 \times 10^{22}) atoms of carbon.
