Chapter 13: Problem 28

Find the molar mass of ammonia (NH \(_{3}\) ).

Short Answer

Expert verified
Answer: The molar mass of ammonia (NH\(_{3}\)) is 17.034 g/mol.

Step by step solution

01

Determine the molar mass of Nitrogen (N)

Find the atomic mass of Nitrogen on the periodic table. The atomic mass of Nitrogen is approximately 14.01 amu. The molar mass of Nitrogen is 14.01 g/mol.
02

Determine the molar mass of Hydrogen (H)

Find the atomic mass of Hydrogen on the periodic table. The atomic mass of Hydrogen is approximately 1.008 amu. The molar mass of Hydrogen is 1.008 g/mol.
03

Calculate the molar mass of NH\(_{3}\)

To calculate the molar mass of ammonia (NH\(_{3}\)), add the molar mass of Nitrogen (N) to three times the molar mass of Hydrogen (H), as there are three Hydrogen atoms in the ammonia molecule: Molar mass of NH\(_{3}\) = Molar mass of N + (3 脳 Molar mass of H) Molar mass of NH\(_{3}\) = 14.01 g/mol + (3 脳 1.008 g/mol) Molar mass of NH\(_{3}\) = 14.01 g/mol + 3.024 g/mol = 17.034 g/mol

If the upper atmosphere of Jupiter has a temperature of \(160 \mathrm{K}\) and the escape speed is \(60 \mathrm{km} / \mathrm{s}\), would an astronaut expect to find much hydrogen there?
The volume of a solid cube with side \(s_{0}\) at temperature \(T_{0}\) is \(V_{0}=s_{0}^{3} .\) Show that if \(\Delta s < s_{0},\) the change in volume \(\Delta V\) due to a change in temperature \(\Delta T\) is given by $$ \frac{\Delta V}{V_{0}}=3 \alpha \Delta T $$ and therefore that \(\beta=3 \alpha .\) (Although we derive this relation for a cube, it applies to a solid of any shape.)
An iron bridge girder $\left(Y=2.0 \times 10^{11} \mathrm{N} / \mathrm{m}^{2}\right)$ is constrained between two rock faces whose spacing doesn't change. At \(20.0^{\circ} \mathrm{C}\) the girder is relaxed. How large a stress develops in the iron if the sun heats the girder to $40.0^{\circ} \mathrm{C} ?$
A tank of compressed air of volume \(1.0 \mathrm{m}^{3}\) is pressurized to 20.0 atm at \(T=273 \mathrm{K}\). A valve is opened and air is released until the pressure in the tank is 15.0 atm. How many air molecules were released?
The driver from Practice Problem 13.3 fills his \(18.9-\mathrm{L}\) steel gasoline can in the morning when the temperature of the can and the gasoline is \(15.0^{\circ} \mathrm{C}\) and the pressure is 1.0 atm, but this time he remembers to replace the tightly fitting cap after filling the can. Assume that the can is completely full of gasoline (no air space) and that the cap does not leak. The temperature climbs to \(30.0^{\circ} \mathrm{C}\) Ignoring the expansion of the steel can, what would be the pressure of the heated gasoline? The bulk modulus for gasoline is $1.00 \times 10^{9} \mathrm{N} / \mathrm{m}^{2}$
