Problem 3-1

How many significant figures are there in the following numbers? (a) 1.903 0 (b) 0.039 10 (c) 1.40 104

Step-by-Step Solution:
Step 1 of 3

For a sample of acetylene collected over water, total gas pressure (adjusted to barometric pressure) is 739 mmHg and the volume is 1033 ml. At the temperature of the gas (24°C), the vapor pressure of water is 20.5 mmHg. How many grams of acetylene are collected Enter to 3 decimal places. 739-20.5=mmHg of acetylene must be changed to atm->718.5(1atm/760mmHg) = 0.94atm PV = nRT (0.94)(1.033L) = n(0.0821)(273+24) = 0.04005molCaCl2(1mol C2H2/1mol CaCl2) = 0.04005molC2H2 0.04005molC2H2(26.04g/1mol) =1.0429g Solid lithium hydroxide is used to "scrub" CO2from the air in spacecraft and submarines; it reacts with the CO2to produce lithium carbonate and water. What volume in liters of CO2at 25°C and 795 torr can be removed by reaction with 429 g of lithium hydroxide Enter to 3 sig figs.
