Hello there!
In this case, according to the given information, it turns out firstly necessary for us to set the equation for the calculation of density and mass divided by volume:
Thus, we can find the mass of the unknown by subtracting the total mass of the liquid to the mass of the flask and the liquid:
So that we are now able to calculate the density in g/mL first:
Now, we proceed to the conversion to lb/in³ by using the following setup:

Mixtures are made up of 2 or more substances that are together in the same place but aren’t chemically bonded.
Answer:
A strong acid will react with a weak base to form an acidic (pH < 7) solution. It depends of the products such as hydrochloric acid, HCl, with sodium hydroxide, NaOH, solutions produces a solution of sodium chloride, NaCl, and some additional water molecules.

Answer:
0.11 atm
Explanation:
Given data
- Temperature (T): -16 °C + 273.15 = 257 K
- Ideal gas constant (R): 0.082 atm.L/mol.K
First, we will calculate the moles (n) of sulfur hexafluoride, considering its molar mass is 146.06 g/mol.
34 g × (1 mol/146.06 g) = 0.23 mol
Then, we can calculate the pressure (P) of sulfur hexafluoride using the ideal gas equation.
P × V = n × R × T
P = n × R × T / V
P = 0.23 mol × (0.082 atm.L/mol.K) × 257 K / 45 L
P = 0.11 atm
