Answer:
Explanation:
Given parameters:
Number of given calories = 614 cal
Note that 1cal = 4.18J
Now to convert the given calories to joule, we use the relationship below:
Since 1Cal gives 4.18Joule of energy
614Cal will produce 4.18 x 614;
2566.52J of energy.
This written as 2.57 x 10³J because it has three significant numbers of 2, 5 and 7.
In writing an operation that involves deducing the significant numbers, we simply express our answer to that shows the lowest number of significant numbers. Our problem has 3 significant numbers each and the answer is given in that regard.
Ideal gas law:
pv = nrt
nr is mole times the ideal gas constant, these are both held constant (do not change value)
pv/t = nr
Then you can set the conditions before = after
pv/t = PV/T
before: (convert to Kelvin)
(0.995)(5.27x10^4) / 305
After: (convert to Kelvin)
(0.720)V / 206.3
solve for V , volume after.
(0.995)(5.27x10^4) / 305 = (0.720)V / 206.3
4.926 x 10^4 L = V
Im not that’s sure because it’s very confusing let me find out wait
Wow that's a lot of stuff for just 10 points you know
The molar mass of ammonium nitrate is 80.04336 g/mol.
