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(1mol)/(105.9888g)=0.3227mol`

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

`0.3227mol\cdot(6.023*10^(23)molecules)/(1mol)=1.9436*10^(23)molecules`

Finally, there are 1.9436x10^23

ANSWER:

34.2g of sodium carbonate = 1.9436 x 10^23
