Answer:
The correct answer is 0.89 mol.
Explanation:
At STP (Standard Temperature and Pressure) conditions, 1 mol of an ideal gas occupies a volume of 22.4 L. If we assume STP conditions, we can consider a convertion factor of 1 mol/22.4 L to convert the volume of NO₂ from liters to moles:
20,00 L x 1 mol/22.4 L = 0.89 mol
So, at STP, we would have 0.89 mol of NO₂
Answer:
22 cubic inches
Explanation:
We are given;
- Mass of titanium = 3.6 pounds
We are required to determine the volume of titanium in cubic inches
- We need to know the density of titanium;
Density of titanium = 4.51 g/cm^3
1 pound = 453.592 g
therefore, 3.6 pound = (3.6 × 453.592 g per pound)
= 1632.93 g
Therefore;
Volume = Mass ÷ density
= 1632.93 g ÷ 4.51 g/cm^3
= 362.069 cm³
But, 1 in³ = 16.387 cm³
Therefore;
Volume = 362.069 cm³ ÷ 16.387 cm³ per in³
= 22.095 in³
= 22 in³
Thus the volume of titanium is 22 cubic inches
