Please help I’m so confused on this it’s stoichiometry

48.27g Na

Explanation:

To start we need to balance the equation. The trick is to make sure both sides have equal amounts of each atom:

2Na + Cl2 --> 2NaCl

Now we can use sociometry

We have 75 g of Cl2, and for every 1 mole of Cl2, there are 70.9 grams:

Now we have moles of Cl2. To get to grams of Na, we need to first use mole to mole ratio:

 From here we convert moles of Na into grams of Na

It's usually easier to just make one singular equation with all of these smaller equations.

The trick to sociometry is making sure your units cancel out until you only have the unit you want. If there are moles of Na in the numerator, there needs to be moles of Na in the denominator. If there are grams of Cl2 in the numerator, there needs to be grams of Cl2 in the denominator and so one and so on

consider the reaction below.
