If the observed value is 4.5 and the true value is 3, then it is 50%
If the observed value is 3 and the true value is 4.5, then it is -33.3%
Answer:
n = m r - r t
Step-by-step explanation:
Solve for n:
m = n/r + t
Hint: | Reverse the equality in m = n/r + t in order to isolate n to the left hand side.
m = n/r + t is equivalent to n/r + t = m:
n/r + t = m
Hint: | Isolate terms with n to the left hand side.
Subtract t from both sides:
n/r = -t + m
Hint: | Solve for n.
Multiply both sides by r:
Answer: n = m r - r t
Amigo hay una aplicación llamada math papá es un calculadora es muy buena si la sabes usar
Answer:
Final volume, V2 = 8.57 liters
Step-by-step explanation:
Given the following data;
Initial volume, V1 = 7.7 liters
Initial pressure, P1 = 6.9 atm
Final pressure, P2 = 6.2 atm
To find the new volume V2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
Substituting into the equation, we have;
![6.9 * 7.7 = 6.2*V_{2}](https://tex.z-dn.net/?f=%206.9%20%2A%207.7%20%3D%206.2%2AV_%7B2%7D%20)
![53.13 = 6.2V_{2}](https://tex.z-dn.net/?f=%2053.13%20%3D%206.2V_%7B2%7D%20)
![V_{2} = \frac {53.13}{6.2}](https://tex.z-dn.net/?f=%20V_%7B2%7D%20%3D%20%5Cfrac%20%7B53.13%7D%7B6.2%7D)
![V_{2} = 8.57](https://tex.z-dn.net/?f=%20V_%7B2%7D%20%3D%208.57%20)
Final volume, V2 = 8.57 liters
Therefore, the new volume is 8.57 liters.
