Answer:
Katie made a mistake. P = (nRT)/P is the correct equation, not V = PnRT
Step-by-step explanation:
The equation for the ideal gas law is PV = nRT, where P is pressure, V is volume, n is the moles of gas, R is the gas constant, and T is the temperature, in Kelvin.
Solving for V:
PV = nRT
V = (nRT)/P
Katie did not solve the equation corretly. To move V from the left to the right side of the equation, she needed to divide both sides by P:
PV = nRT
PV/V = (nRT)/P
P = (nRT)/P is the correct equation
Answer:
<h2><u>
x=−3/7</u></h2>
Step-by-step explanation:
Let's solve your equation step-by-step.
34x=27x−3
Step 1: Subtract 27x from both sides.
34x−27x=27x−3−27x
7x=−3
Step 2: Divide both sides by 7.
7x\7=−3\7
x=−3/7
The answer is 15 percent.
5290-4600=690
690/4600=0.15
Covert the 0.15 into percent which is 15 percent
15/5 = 3
Flour = 3/8 x 3 = 9/8 = 1 1/8 cups.
Chocolate chips = 1/2 x 3= 3/2 = 1 1/2 cups.
Butter = 4/5 x 3 = 12/5 = 2 2/5 cups.
Teaspoons of salt = 4/16 = 1/4 = 1/4 x 3 = 3/4
Earthworms = 1.5 = 3/2 x 3 = 9/2 = 4 1/2 cups.
