For this problem, we should use the Henry's Law formula which is written below:
P = kC
where
P is the partial pressure of the gas
k is the Henry's Law constant at a certain temperature
C is the concentration
Substituting the values,
1.71 atm = (7.9×10⁻⁴<span> /atm)C
Solving for C,
C = 2164.56 molal or 2164.56 mol/kgwater
Let's make use of density of water (</span>1 kg/1 m³) and the molar mass of NF₃ (71 g/mol).<span>
Mass of NF</span>₃ = 2164.56 mol/kg water * 1 kg/1 m³ * 1 m³/1000000 mL * 150 mL * 71 g/mol = 23.05 g
Yes, a reaction will occur. Potassium chloride react with bromine to produce potassium bromide and chlorine would take place in a boiling solution.
That means that one mole of sulfur has a mass of 32.065 grams. b) This compound contains two hydrogen atoms and one oxygen atom. To find the molar mass of H2O, we need to add the mass of two hydrogen atoms plus the mass of one oxygen atom. We get: 2(1.008)+16.00=18.016g/mol.
Hey there!
First we need to find the molar mass of Ca(OH)₂.
Ca: 1 x 40.078
O: 2 x 16
H: 2 x 1.008
----------------------
74.094 grams
Find how many moles are in 523 grams of Ca(OH)₂.
523 ÷ 74.094 = 7.06 moles
There are 2 atoms of oxygen in each molecule of Ca(OH)₂.
7.06 x 2 = 14.12
523g of Ca(OH)₂ contains 14.12 moles of oxygen.
Hope this helps!
