According to Boyle's law, PV = k, what was the pressure to the nearest tenth at the time of the first measurement given the following information?
V1
= 7,450 mL
P2
= 8.25 atm
V2
= 1,645 mL
a. 37.4atm
b. 4.52atm
c. 0.5atm
d. 1.8atm
To find the pressure P1 at the time of the first measurement, we can use Boyle's law equation:
P1V1 = P2V2
P1 = (P2V2) / V1
P1 = (8.25 atm * 1,645 mL) / 7,450 mL
P1 = 1.82 atm
Therefore, the pressure at the time of the first measurement was approximately 1.8 atm. So the correct answer is:
d. 1.8 atm
