Question

34.2g SODIUM CARBONATE TO MOLECULES

Answer 1

INFORMATION:

We have 34.2g of sodium carbonate, and we must convert to molecules

STEP BY STEP EXPLANATION:

To convert to molecules, we need to:

1. Calculate the number of moles in the 34.2 g of sodium carbonate, using that the molar mass of sodium carbonate is 105.9888 g/mol

$34.2g\cdot\frac{1mol}{105.9888g}=0.3227mol$

2. Using the moles, we can calculate molecules multiplying by 6.023x10^23/mol

$0.3227mol\cdot\frac{6.023\times10^{23}molecules}{1mol}=1.9436\times10^{23}molecules$

Finally, there are 1.9436x10^23

ANSWER:

34.2g of sodium carbonate = 1.9436 x 10^23
