Annually cumulating interest can be determined by the following formula:

r represents the interest rate as a decimal, and P represents the starting amount of money.
Make an equation:
6x + 12 = 268.26
6x = 256.26
X = $42.71
The monthly payment is $42.71
We first assume that this gas is an ideal gas and we use the ideal gas equation to determine the answer. It is expressed as:
PV = nRT
Molar volume can be obtained from the equation by V/n.
V/n = RT/P
Therefore, the correct answer from the choices listed above is option A, <span>at 273 K and at 2.0 atm.</span>
Answer:
17
Step-by-step explanation:
multiply both sides of the equation by 8
k + 31 = 48
move the constant to the right-hand side and change its sign
k = 48 - 31
subtract the numbers
k = 17
