What mass (in grams) of cobalt(II) nitrate hexahydrate is needed to
make 100.0mL of 0.10M cobalt(II) nitrate solution?
Solutions
Expert Solution
moles of cobalt(II) nitrate solution = molarity x volume
= 0.10 x 100 / 1000
= 0.01
Molecular Weight cobalt(II) nitrate hexahydrate = 291.03 g / mol
moles = mass / molar mass
mass = moles x molar mass
= 0.01 x 291.03
= 2.91 g
mass of cobalt(II) nitrate hexahydrate = 2.91 g

Water is Unusual because...(Choose All true)
- soilid phase is less compact than the liquid phase.
-Most molecules as small as water are gases at room
temperature
-most molecules as small as water have higher boiling points
than water does
-its very strong hydrogen bonding and polarity (among other
things) give it unusual properties
