What is the mass of 7.8 x 1018 carbon atoms?
3.011 x 1023 atoms of carbon will weigh about 6 grams One mole of carbon atoms weighs 12.011 grams, and there are 6.022 x 1023 atoms in a moles. So you have half as many atoms, so the mass would be half as much or 6.0055 grams to be precise.
How many atoms of carbon are in a pure sample of carbon having a mass of 72.0 g?
72.0 grams Carbon (1 mole C/12.01 grams)(6.022 X 10^23/1 mole C) = 3.61 X 10^24 atoms of carbon
How many atoms of 12Carbon are in a 3.50 g sample of this particular isotope?
3.50 grams carbon 12 (1 mole C(12)/12.0 grams)(6.022 X 10^23/1 mole C(12)) = 1.76 X 10^23 atoms
How many carbon atoms are in 77.28g of ethane?
77.28 grams C2H6 (1 mole C2H6/30.068 grams)(2 mole C/1 mole C2H6)(6.022 X 10^23/1 mole C) = 3.096 X 10^24 atoms of carbon
How many carbon atoms are in 10 pounds of C12H22O11?
10 pounds C12H22O11 (454 grams/1 pound)(1 mole C12H22O11/342.296 grams)(12 mole C/1 mole C12H22O11)(6.022 X 1023/1 mole C) = 9.6 X 1025 atoms of carbon =====================
How many atoms are in 17 grams of carbon?
17 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 8.5 X 1023 atoms of carbon =====================
How many carbon atoms are there in 31.8 grams of carbon?
31.8 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C)= 1.59 X 1024 atoms of carbon===================
How many atoms are in 1.9 g Carbon?
Atomic mass of carbon: 12.0 grams1.90 grams × (6.02 × 1023 atoms) / (12.0 grams) = 9.53 × 1022 atoms C
How many atoms are in 1.7 g C?
1.7 grams * (1mole/ 12.011 grams) * (6.023x 10^23 atoms/ 1 mole) =8.525 * 10^ 22 atoms carbon round to 2 sig. figs
how many hydrogen atoms are in 800 grams of C3H8?
So, there are approximately 8.74 × 1 0 24 8.74×10 24 hydrogen atoms in 800 grams of C 3 H 8 C 3 H 8 .
What is the mass of 7.8 x 1018 carbon atoms?
3.011 x 1023 atoms of carbon will weigh about 6 grams One mole of carbon atoms weighs 12.011 grams, and there are 6.022 x 1023 atoms in a moles. So you have half as many atoms, so the mass would be half as much or 6.0055 grams to be precise.
How many carbon atoms are present in 0.5 carat?
0.5 carat carbon (0.2 grams/1 carat)(1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 5.0 X 1021 atoms of carbon ===================
What is the mass in grams of 4350000 atoms of carbon?
Not that much!! 4350000 atoms Carbon (1 mole C/6.022 X 10^23)(12.01 grams/1 mole C) = 8.675 X 10^-17 grams
How many carbon atoms are in 2.6g of graphite pure carbon?
2.6 grams graphite ( just carbon ) (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 1.3 X 1023 atoms of carbon in that mass graphite ================================
How many atoms in 1000 g of carbon?
For this problem, the atomic mass is required. Take the mass in grams and divide it by the atomic mass. Then multiply it by Avogadro's constant, 6.02 × 1023.1000 grams C / (12.0 grams) × (6.02 × 1023 atoms) = 5.02 × 1025 atoms
How many carbon atoms does it take to equal 12.011 grams?
Carbon is equal to 12.01 grams. 1.) determine how many moles of carbon are there in the mass given. Just use the conversion method. In this case, 12.011 g C x ( mol C / 12.01 g C) = 1 mole of C 2.)Acc to Avogadro's number, one mole of any element is equal to 6.02 x 10^23 atoms. there is one mole of Carbon is 12.01 grams, therefore, it takes 6.01x10^23 atoms.
How many atoms are in 12g of carbon?
That is about the mole definition of Avogadro's number, so. 6.022 X 10^23 atoms of carbon
