Explanation:

Molarity = mol/L or g/L

Data:

Mass>80.0g

Mr of CaCl2>111.1g/mol

V>500mL

Convert mL to Litres;. mole=g/Mr

1L=1000mL. =80g/111.1g/mol

x=500mL. =0.720072007mol

x=0.5L

Molarity= mole/volume

=0.720072007mol/0.5L

=1.440144014mol/L

=1.4401mol/L

Hope this helps. Depending on the question you can also find it in g/L but mol/L is safer.

How do you do these?
Agata [3.3K]

Solve these problems like weighted averages:

The first one:

Multiply the masses (isotope numbers) by the decimal form of the percentage. Add them

0.076 (6) + 0.924 (7) = 6.924


The second one:

0.2 (10) + 0.8 (11) = 10.8


If you think about it, these answers make sense. 6.924 is much closer to 7 than to 6 (since there's a lot more lithium-7 than there is lithium-6). 10.8 is closer to 11 than to 10.
