Well assuming we have all of these, earth
Answer:
CH4+ 2Cl2→CH2Cl2+ 2HCl
Explanation:
mass is 132.8`125
as methane and dichlormethane has the same molar ration 1 to 1
mol of ch4 is 1.5625
so 1.5625 times mr of ch2cl2 is 132.8125
Hello!
To find the mass in grams of 2.00 * 10²³ molecules of F₂ you'll need to apply the
Avogadro's number, which tells the number of molecules in a mol of a substance, and the
Molar Mass, which tells the weight of a mole of a substance. These two quantities are used in the following conversion factor:

So, the mass of 2.00 * 10²³ molecules of F₂ is
12,51 gHave a nice day!
P = 1.5atm ≈ 1519.88hPa
V = 8.56L
R = 83.1 [hPa*L] / [mol*K]
T = 0°C =273K
pV = nRT |:RT
n = pV / RT
n = [1519.88hPa*8.56L] / [83.1 [hPa*L] / <span>[mol*K] * 273K]
n </span>≈ <u>0.57mol</u><span><u> </u></span>
