What is the maximum amount of HCl, in grams, that can be produced if 37.5 g of BCl3 and 60.0 g of H2O are reacted according to t
Rus_ich [418]
Ooooh boy alright. So, this may or may not be a limited reactant problem so we need to first find out of it is.

First, how many moles of each substance are there

the molar mass of BCl3 is <span>117.17 grams so 37.5 g / 117.17 is ~ .32 mol.
The molar mass of H2O is 18.02 so 60 / 18.02 is ~ 3.33 mol.

Now, for every 1 mole of BCl3, there are 3 moles of HCl created. Therefore, BCl3 can create ~ .96 moles.
For every 3 moles of H2O, there are 3 moles of HCl created. Therefore, HCl can create ~3.33 moles.

But, there is not enough BCl3 to support that 3.33 moles, only enough for .96 moles, therefore BCl3 is the limiting reactant. Now, to answer the question, simply multiply .96 moles by the molar mass of HCl.

.96 x 36.46 = ~35 g</span>

Determine the mass of KNO3 that dissolves in 100 grams of water at 40°C to produce a saturated solution
velikii [3]
From a solubility curve the solubility of KNO3 at 40°C is about 63 g / 100 g of water.


That means that 100 g of water at 40°C can dissolve 63 g of KNO3.


A saturated solution is one that cannot dissolve more solute, because it already has reached the greatest concentration that it can hold.


Then, the mass of KNO3 that dissolves in 100 g of water is about 63 g.
