Answer:
Explanation:
Let final temperature be T .
vapor is at 102⁰C
loss of heat by vapor in turning into water at 100⁰C
= 2.6 x 2 x 1.996 + 2.6 x 2260 = 5886.37 J
loss of heat to lower temperature to T
2.6 x 4.186 x ( 100 - T )
1088.36 - 10.88 T
Total heat loss = 5886.37 + 1088.36 - 10.88 T
= 6974.73 - 10.88 T
heat gain by silver to gain temperature from 1⁰C to T⁰C
= 1250 x ( T - 1 ) x .235 = 293.75 T - 293.75
heat gain = heat loss
293.75 T - 293.75 = 6974.73 - 10.88 T
304.63 T = 7268.48
T = 23.86°C .
Is this multi choice or no?
The correct answer among all the other choices is C) 36.76 grams. This is the molar mass of gas A if the molar mass of gas B is 17 grams. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
