I’m gonna be honest I’m just answering So I could upload my question
H2So4 is a strong acid and a strong electrolyte which means that when this dissociates in water, the dissociation process is complete. The first dissociation is
H2 SO4 = H + HSO4-
This can further release H+ and dissociate SO4- instead already
Answer:
The answer to your question is 0.13 M
Explanation:
Data
[HNO₃] = ?
moles of HNO₃ = 9.8 x 10⁻²
volume = 705 ml
Process
1.- Convert volume to milliliters
1000 ml ------------------ 1 L
705 ml ------------------ x
x = (705 x 1) / 1000
x = 705 / 1000
x = 0.75 L
2.- Calculate the molarity
Molarity = moles / volume
Molarity = 9.8 x 10⁻² / 0.75
Molarity = 0.13
<span>B) Boiling point Elevation states a solution typically has a measurably higher than a pure solvent . So would be B. </span>
Answer:
1.61 atm
Explanation:
Using general gas law equation as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
From the information provided in this question,
V = 5.00L
T = 350K
mass of O2 = 9.00g
Using mole = mass/molar mass
Molar mass of O2 = 16(2) = 32g/mol
mole = 9/32
mole = 0.28mol
Using PV = nRT
P = nRT/V
P = 0.28 × 0.0821 × 350/5
P = 8.0458/5
P = 1.609
Pressure = 1.61 atm
