Answer:
How can drying a hydrate help you determine its mole ratio of water to salt?
Explanation:
Answer:
If two atoms get close enough together then the electrons of each atom will be attracted to both nuclii. If the atoms get two close then the nuclii will repell each other. Single sided arrows represent attraction.
Explanation:
Answer:
<u><em>5.74M or 5.74 mol/L (to 3 sign. fig.)</em></u>
Explanation:
The molar mass of NaNO3 is 85g/mol, which means that:
1 mole of NaNO3 - 85g
? moles - 122.0g
= 122/85 = 1.44 moles
Concentration in mol/L = no. of moles (moles) ÷ volume (L)
=<em> 5.74M or 5.74 mol/L (to 3 sign. fig.)</em>
