Explanation / Answer

1)

temperrature = 110 C = 383 K

volume = 350 ml = 0.35 L

pressure = 760 mm Hg = 1 atm

P V = n R T

1 x 0.35 = n x 0.0821 x 383

n = 0.011

moles of CO2 present = 0.0111 moles

2)

pressure P1 = 740 mmhg = 0.974 atm

volume = 6.00 L

temperature = 380 K

at stp conditions

pressure P2 = 1 atm

temperature = 273 K

P1V1 / T1 = P2 V2 / T2

0.974 x 6 / 380 = 1 x V2 / 273

V2 = 4.20

volume at STP = 4.20 L
