Answer:
im no expert i believe 42
hope it helps
Explanation:
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
2 g/cm³ is the density of the block of wood
Explanation:
To determine density of the block of wood we use the following formula:
density = mass / volume
density of the wood block = 100 g / 50 cm³
density of the wood block = 2 g/cm³
