Answer:
0.013 mole
Explanation:
Step 1:
Data obtained from the question. This includes:
Volume (V) = 250 mL
Pressure (P) = 1.3 atm
Temperature (T) = 33°C
Number of mole of (n) =?
Step 2:
Conversion to appropriate units.
The volume and the temperature given in the question must be converted to their appropriate unit in order to obtain the answer to the question in the right unit.
For volume:
We must, convert mL to L
1000 mL = 1 L
Therefore, 250 mL = 250/1000 = 0.25 L
For temperature:
We, must convert °C to K.
K = °C + 273
K = 33°C + 273
K = 306K
Step 3:
Determination of the number of mole of CO2.
Applying the ideal gas equation:
PV = nRT
The number of mole of CO2 can be obtained as follow:
V = 0.25 L
P = 1.3 atm
T = 306K
R (gas constant) = 0.082atm.L/Kmol
Number of mole of (n) =?
PV = nRT
1.3 x 0.25 = n x 0.082 x 306
Divide both side by 0.082 x 306
n = (1.3 x 0.25) /(0.082 x 306)
n = 0.013 mole

Answer:
The pointer pointing to the grey and white balls are either proton or nuetron i van't really tell cause their grey and white.
The whole clster of balls is the Nucleus
The black balls on the lines are electrons
And the lines are the energy level
Explanation:
Answer:
1 M
Explanation:
Molarity is moles per liter (mol/L).
You have 3 moles of HCl in 3 L of water. Divide the two values.
(3 mol)/(3 L)
= 1 mol/L
= 1 M
