There are approximately 3.633 x 10^23 carbon atoms in 21.84 grams of carbon.
28.5 g (6.02 x 1023 at / 12.01 g) = 1.43 x 1024atoms
4 grams C4H10 (1 mole C4H10/58.12 grams)(4 mole C/1 mole C4H10)(6.022 X 10^23/1 mole C) = 1.7 X 10^23 atoms of carbon ( may want 2 X 10^23, for sigi figi ) ----------------------------------------
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.
There are 2.92 x 10^22 atoms of 12Carbon in a 3.50 g sample, which is calculated by first determining the molar mass of 12Carbon (12.00 g/mol), then using Avogadro's number to convert from grams to atoms.
To calculate the number of carbon atoms in 25.0 grams of dipyrithione, you first need to determine the molar mass of dipyrithione (C10H8N2O2S2). From there, you can find the moles of dipyrithione in 25.0 grams. Finally, using the chemical formula, you can determine the number of carbon atoms in that amount of dipyrithione.
17 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 8.5 X 1023 atoms 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===================
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 .
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 ===================
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
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.
5.34 grams W(CO)6 (1 mole W(CO)6/351.86 grams)(6 moles C/1 mole W(CO)6)(6.022 X 1023/1 mole C) = 5.48 X 1022 atoms of carbon ========================
28.5 g (6.02 x 1023 at / 12.01 g) = 1.43 x 1024atoms
A karat ( or carat ) is = to 0.20 grams so; 1.92 Karats carbon (0.20 grams/1 karat)(1 mole C/12.01 grams)(6.022 X 10^23/1 mole C) = 1.93 X 10^22 atoms of carbon in 1.92 karats
That is about the mole definition of Avogadro's number, so. 6.022 X 10^23 atoms of carbon
35.2 grams C6H8O (1 mole C6H8O/96.124 grams)(6.022 X 1023/1 mole C6H8O)= 2.21 X 1023 atoms of vitamin C===========================
There are 1.9 grams of Carbon. The molar mass of carbon is approximately 12 grams per mole. This means there are ~0.158 moles of carbon. Since 1 mole of carbon contains Avogadro's number of atoms (~6.022 x 10^23 atoms), then 0.158 moles would contain ~9.53 x 10^22 atoms.
