Answer : The number of molecules present in nitrogen gas are,
Explanation :
First we have to calculate the moles of nitrogen gas by using ideal gas equation.
where,
P = Pressure of
gas =
(1 atm = 760 mmHg)
V = Volume of
gas = 985 mL = 0.982 L (1 L = 1000 mL)
n = number of moles
= ?
R = Gas constant =
T = Temperature of
gas =
Now put all the given values in above equation, we get:

Now we have to calculate the number of molecules present in nitrogen gas.
As we know that 1 mole of substance contains
number of molecules.
As, 1 mole of
gas contains
number of molecules
So,
mole of
gas contains
number of molecules
Therefore, the number of molecules present in nitrogen gas are,
Answer:
The answer is b
Explanation:
have common properties and are good conductors of heat and electricity. They reflect light and are malleable, and ductile.
The answer you’re looking for is 0.250
Solute is something that is being dissolved { ex : sugar , salt}
Solvent is something that has ability to dissolve things { ex : water}
False because the solvent is present in larger amounts...
