Answer:
0.5 M
Explanation:
First we have to start with the <u>molarity equation</u>:
We need to know the<u> amount of moles and the litters</u>.
If we have 100 mL we can convert this value to “L”, so:
Now we can continue with the moles, for this we have to know the <u>formula of sodium sulfate</u> 
, with this formula we can <u>calculate the molar mass</u> if we know the atomic mass of each atom on the formula (Na: 23 g/mol, S: 32 g/mol, O: 16 g/mol). We have to multiply each atomic mass by the amount of atoms in the formula, so:
In other words:
Now we can <u>calculate the moles</u>:
Finally, we can <u>calculate the molarity:</u>
I hope it helps!
Alright well is u just want the Answer then
33k - 15 Hope this helps :)
If you want i can add more detail :)
Answer:
8000 metres is equal to 4.971 miles
