Given the following equation 2K +Cl2 --> 2KCl,
how many molecules of KCl from 1.00 g of Cl2 and excess K?

australopithecus · Answer

can you convert grams of Cl2 to moles?

allieatthedisco · Answer

4.21 mol, i think

australopithecus · Answer

Sorry that is Wrong

The molecular mass of chloride is 35.453g/mol from the periodic table

Cl2 has two atoms of chlorine thus its molecular mass is,
35.453g/mol+35.453g/mol = 70.906g/mol

Now we can sub it into the formula,

$$Moles = \frac{Grams}{MolecularMass}$$

australopithecus · Answer

The first thing you do in these problems is solve for moles

Tell me what you get and I will tell you if you are on the right track then we can move onto the next step

allieatthedisco · Answer

okay, so, i would have 70. 9 mol = 1 gram/ 74.5?

No

australopithecus · Answer

A larger number in the denominator than in the numerator indicates a smaller number.

How many times does 70.906 go into 1
