From the ideal gas law, PV = nRT, we can rearrange the equation to solve for T given the other parameters.
T = PV/nR
where P = 0.878 atm, V = 1.20 L, n = 0.0470 moles, and R = 0.082057 L•atm/mol•K. Plugging in our values, we obtain the temperature in Kelvin:
T = (0.878 atm)(1.20 L)/(0.0470 mol)(0.082057 L•atm/mol•K)
T = 273 K
So, the second answer choice would be correct.

Answer:
We have to add 14 mL of water to dilute the alcohol solution from 13% to 6%
Explanation:
Step 1: Data given
Original solution has 12 mL of 13% alcohol
New volume has a concentration of 6%
Step 2: Determine how much pure alcohol you have in the solution.
0.13 * 12ml = 1.56 ml pure alcohol.
Step 3: Calculate ratio alcohol: total in volume
1.56 ml / 12 ml = .013
Step 4: add water to the total solution and set the desired percentage
1.56 ml / (12ml + x) = 0.06
1.56 = 0.06 (12 + x)
1.56 = 0.72 + 0.06x
0.84 = 0.06x
x = 14
We have to add 14 mL of water to dilute the alcohol solution from 13% to 6%
Answer:
convection
Explanation:
as air is heated, it rises up and away from the heat source, cools then falls closer to the heat source over and over again.
