Answer: air
Explanation:since individual components of air cannot be identified by merely looking at it, it is a homogeneous mixture.
Answer:
The answer to your question is n = 6.24 moles
Explanation:
Data
Volume = 150 l
moles = ?
Temperature = 20°C
Pressure = 1 atm
R = 0.082 atm L / mol°K
Process
1.- Convert temperature to °K
T = 20 + 273 = 293°K
2.- Use the formula of ideal gases
Formula
PV = nRT
-Solve for n
n = PV/RT
-Substitution
n = (1)(150) / (0.082)(293)
-Simplification
n = 150 / 24.026
-Result
n = 6.24 moles
I’m assuming the cordial is cocoa, two cups equals a pint. So he should add 1 pint or 2cups of water. Whichever measurement you need.
