Problem: Nickel carbonyl, Ni(CO)4 is one of the most toxic substances known. The present maximum allowable concentration in laboratory air during an 8-hr workday is 1 ppb (parts per billion) by volume, which means that there is one mole of Ni(CO)4 for every 109 moles of gas. Assume 24 oC and 1.00 atm pressure. What mass of Ni(CO)4 is allowable in a laboratory that is 14ft x 22ft x 11ft?

🤓 Based on our data, we think this question is relevant for Professor Windman's class at MC MARICOPA.

Step 1

volume = 14 ft×22 ft × 11 ftvolume = 3388 ft3 ×(1 m3.281 ft)3 × 103 L1 m3

volume = 95923 L


Step 2

T = 24°C + 273.15 = 297.15 K
