Answer:
Approximately 1.9 kilograms of this rock.
Explanation:
Relative atomic mass data from a modern periodic table:
To answer this question, start by finding the mass of Pb in each kilogram of this rock.
89% of the rock is
. There will be 890 grams of
in one kilogram of this rock.
Formula mass of
:
.
How many moles of
formula units in that 890 grams of
?
.
There's one mole of
in each mole of
. There are thus
of
in one kilogram of this rock.
What will be the mass of that
of
?
.
In other words, the
in 1 kilogram of this rock contains
of lead
.
How many kilograms of the rock will contain enough
to provide 1.5 kilogram of
?
.
I think it's Molality because the moles of solute over the kilograms of solvent is equal to the molality...
Answer:
The high system pressure and relatively large chlorine molecule size.
Explanation:
Having the expression of the ideal gas, and clearing the pressure, we have:
P = nRT/V
Meanwhile, for a non-ideal gas we have the following equation:
P = (nRT / V-nb) - n2a/V2
In this equation, high pressures and low temperatures have an influence on nonideal gases.
Therefore, at high pressures, the molecules in a gas are closer together and have high intermolecular forces. On the other hand, at low temperatures, the kinetic energy of a gas is reduced, so that the intermolecular attractive forces are also reduced.
Answer:
69.8 kilo Pasacl is the pressure of the hydrogen gas.
Explanation:

Pressure at which hydrogen gas collected = p = 101.2 kilo Pascals
Vapor pressure water =
= 31.4 kilo Pascals
The pressure of hydrogen gas = P
The pressure at which gas was collected was sum of vapor pressure of water and hydrogen gas.


69.8 kilo Pasacl is the pressure of the hydrogen gas.
