Answer:
4.1 moles
Explanation:
Applying
PV = nRT................ equation 1
Where P = pressure, V = volume, n = number of moles, R = molar gas constant, T = Temperature.
make n the subject of the equation
n = PV/RT.............. Equation 2
From the question,
Given: V = 35 L , P = 2.8 atm, T = 15 °C = (15+273) = 288 K, R = 0.083 L.atm/K.mol
Substitute these values into equation 2
n = (35×2.8)/(0.083×288)
n = 4.1 moles
<u>False</u> is the correct answer.
Sugar is an example of a compound, while koolaid is an example of a homogeneous mixture (more specifically, a solution). A compound is a combination of 2 or more different kinds of atoms chemically bonded in a set ratio. A mixture is a combination of 2 or more substances.
answer is koolaid is a mixture
