Answer:
197 + (35.5×3) = 303.5
Explanation:
relative formula mass is the sum of the relative atomic masses of the atoms in the formula ( AuCl3 )
According to Gases law, we know,
PV/T = Constant
So, P₁V₁/T₁ = P₂V₂/T₂
Here, P₁ = 108 kPa
V₁ = 592.2 mL
T₁ = 10+273 = 283 K
P₂ = ?
V₂ = 750 mL
T₂ = 28.9+273 = 301.9
Substitute their values,
108 * 592.2 / 283 = P₂ * 750 / 301.9
P₂ = 63957.6 * 301.9 / 283 * 750
P₂ = 19308799.44 / 212250
P₂ = 90.97 kPa
In short, Your Final Answer would be: 90.97 kPa
Hope this helps!
Answer:
6.39 × 10⁻³ M
Explanation:
First, we will calculate the moles of HCl using the ideal gas equation.
P × V = n × R × T
n = P × V / R × T
n = 1.06 atm × 0.222 L / 0.0821 atm.L/mol.K × (26.0 + 273.15) K
n = 9.58 × 10⁻³ mol
The molar concentration of HCl is:
M = moles of HCl / liters of solution
M = 9.58 × 10⁻³ mol / 1.5 L
M = 6.39 × 10⁻³ M
Answer: 27.5 liters
Explanation:
To calculate the moles, we use the equation:
For
Given mass = 100.0 g
Molar mass of = 122.5 g/mol
Putting values in above equation, we get:
2 moles of produces 3 moles of
0.82 moles of produces = moles of
Volume of
Thus 27.5 liters of are produced by the complete decomposition of 100.0 g of at STP
