Answer:
0.895 g/mL
Explanation:
Step 1: Given data
Mass of liquid Z (m): 2.763 lb
Volume of liquid Z (V): 5.93 cups
Step 2: Convert "m" to grams
We will use the relationship 1 lb = 453.59 g.
Step 3: Convert "V" to milliliters
We will use the relationship 1 cup = 236.59 mL.
Step 4: Calculate the density of the liquid Z
The density (ρ) of the liquid Z is equal to its mass divided by its volume.
We need to make sure that the pressure is in the same units.
let's convert the atm to mmHg. remember that 1 atm= 760 mmHg
1.03 atm (760 mmHg/ 1 atm)= 783 mmHg
to find the pressure of the gas, you just need to subtract the values
pressure of gas= 783 - 305 = 478 mmHg
The answer is (3), oxidation occurs at the anode and reduction occurs at the cathode. That's because the oxidation reaction can lose electrons and reduction can gain electrons.
Answer:
Maybe later, not right now. Tell you when.
