Assuming that the change of volumen was done at constant pressure and the quantity of gas did not change, you use Charles' Law of gases, which is valid for ideal gases:
V / T = constant => V1 / T1 = V2 / T2 => V1 = [V2 / T2] * T1.
Now plug in the numbers ,where T1 and T2 have to be in absolute scale.
T1 = 38.1 + 273.15 K = 311.25K
T2 = 15.0 + 273.15 K = 288.15K
V1 = 4.5L * 311.25K / 288.15 K = 4.86L.
Answer: 4.86
Answer:
0.225M
Explanation:
Step 1:
Data obtained from the question. This includes:
Volume of the stock solution (V1) = 125mL
Molarity of the stock solution (M1) = 0.90 M
Volume of the diluted solution (V2) = 125 + 375 = 500mL
Molarity of the diluted solution (M2) =..?
Step 2:
Determination of the molarity of the diluted solution.
This is obtained by using the dilution formula as follow:
M1V1 = M2V2
0.9 x 125 = M2 x 500
Divide both side by 500
M2 = (0.9 x 125) /500
M2 = 0.225M
Therefore, the molarity of the diluted solution is 0.225M
Answer: negative acellaration or mass.
Explanation:
the first reason why is that i got that quistion right. and when objects are unbalanced it gives negative acellaration
You can have as many controls as necessary, But they must remain equal at all times in order to get the most accurate results
