1 carot = 0.2 grams
1.5 carot = 0.3 grams.
1 mol of Carbon = 12 grams
x mol = 0.3 grams
0.3 * 1 = 12 x
x = 0.3/12
x = 0.025 mol
1 mol of Carbon is 6.02 * 10^23 atoms
0.025 mol of carbon is x
1/0.025 = 6.02*10^23 * /x
x = 0.025 * 6.02 * 10^23
x = 1.5 * 10^22 atoms of carbon.
The answer is A (The ability to react with oxygen)
Answer:
What about em
Explanation:
Aren't metals cations and non metals anions
1) Chemical equation
Cu + 2AgNO3 ---> Cu (NO3)2 + 2Ag
2) molar ratios
1 mol Cu: 2 moles AgNO3 : 1 mol Cu (NO3)2 : 2 mol Ag
3) Convert 12. 83 * 10^23 atoms of Cu in moles
12.83 * 10 ^ 23 atoms / (6.02 * 10^23 atoms / mol) = 2.131 mol Cu
4) Use the proportions
2.131 mol Cu * 2 mol Ag / 1 mol Cu = 4.262 mol Ag
5) Use the atomic mass of silver to convert 4.262 mol in grams
mass = number of moles * atomic mass = 4.262 mol * 107.9 g / mol = 459.9 grams
Answer: 459.9 g
