Answer:
C. the relative molecular mass of the compound
Explanation:
Like molecular formulas, empirical formulas are not unique and can describe a number of different chemical structures or isomers. <u>To determine an empirical formula, the relative molecular mass of the composition of its elements</u> can be used to mathematically determine their ratio.
Answer:
The final volume of the sample of gas
= 0.000151 
Explanation:
Initial volume
= 200 ml = 0.0002
Initial temperature
= 296 K
Initial pressure
= 101.3 K pa
Final temperature
= 336 K
Final pressure
= K pa
Relation between P , V & T is given by

Put all the values in the above equation we get

= 0.000151 
This is the final volume of the sample of gas.
Answer:
The final temperature of the setup = 36.6°C
Explanation:
Let the final temperature of the setup be T
Heat lost by the copper tubing = Heat gained by water and the vessel
Heat lost by the copper tubing = mC ΔT = 455 × 0.387 × (89.5 - T) = (15759.61 - 176.1T) J
Heat gained by water = mC ΔT = 159 × 4.186 × (T - 22.8) = (665.6T - 15175.1) J
Heat gained by vessel = c ΔT = 10 × (T - 22.8) = (10T - 228) J
Heat lost by the copper tubing = Heat gained by water and the vessel
(15759.61 - 176.1T) = (665.6T - 15175.1) + (10T - 228)
851.7 T = 31162.71
T = 36.6°C
(2.5)(10000)=25000
25000 * 3785
ML = 94635294.6 milliliters
