Calculate the mass of chloroform that contains 1.00X10^12 molecules of chloroform
Brums [2.3K]

<span>Molar mass of chloroform (CHCl3)
C = 1 * 12 = 12 a.m.u
H = 1 * 1 = 1 a.m.u
Cl = 3 * 35.5 = 106.5 a.m.u
 Molar Mass (CHCl3) = 12 + 1 + 106.5 = 119.5 g / mol
 
Knowing that: The value of Avogadro's constant corresponds to approximately </span>6,02*10^{23} molecules, if chloroform contains 1,00 * 10^{12} molecules. <span> 
We have:
 
</span>1,00 * 10^{12} * 6,02 * 10^{23} = 6,02 * 10 ^ {35} molecules<span>
 
Now, how many grams are there in the chloroform molecule?

grams -------- molecules</span><span>
119,5 </span>→ 6,02 * 10^{23}
x → 6,02 * 10^{35}

6,02 * 10 ^ {23} * x = 119,5 * 6,02 * 10 ^{35}
6,02 * 10 ^ {23}x = 719,39 * 10^{35}
x =  \frac{719,39}{6,02}*10^{35-23}
\boxed{x = 119,5*10^{12}grams}
