Answer:
181.12 moles
Explanation:
V = 3.35L
T = 105°C = (105 + 273.15)K = 378.15K
P = 170.0kPa = 170.0*10³Pa (1kPa = 1000Pa)
R = 8.314J /mol.K
n = ?
From ideal gas equation,
PV = nRT
P = pressure of the gas
V = volume of the gas
n = number of moles
R = ideal gas constant
T = temperature of the gas
PV = nRT
n = PV / RT
n = (170*10³ * 3.35) / (8.314 * 378.15)
n = 569500 / 3144.317
n = 181.12 moles
Answer:
Strong acids have mostly ions in solution, therefore the bonds holding H and A together must be weak. Strong acids easily break apart into ions. Weak acids exist mostly as molecules with only a few ions in solution, therefore the bonds holding H and A together must be strong
Depends how much sugar are you talking about. If we are under the solubility concentrations of sugar no change or very little change can be observed in the volume of the solution. The sugar molecules will occupy the intermolecular spaces of the water molecules
Answer:
<h2>mass = 19.98 g</h2>
Explanation:
To find the mass of 1.11 mol of H2O we must first find it's molecular mass after that we use the formula
<h3>m = M × n</h3>
where
m is the mass
M is the molecular mass
n is the number of moles
From the question
n = 1.11 mol
Taking
M( H) = 1 g/mol , M(O) = 16 g/mol
We have
M( H2O) = 2 + 16 = 18 g/mol
So we have
m = 1.11 × 18
We have the final answer as
<h3>mass = 19.98 g</h3>
Hope this helps you
