The concentration of carbon monoxide in an urban apartment is 49 µg/m^{3}. What mass of carbon monoxide in grams is present in a room measuring 8 ✕ 12 ✕ 22 ft? (Enter your answer to three digits.) Explain

Thank you for the opportunity to help you with your question!

Step 1 Find the volume in Cubic Feet. V = l*w*h V = 8 * 12 * 22 V = 2112 cu feet. Step 2 Convert this to cubic meters Conversion Factor 1 m^3 = 35.315 ft^3 1 m^3 = 35.315 ft^3 x = 2112 ft^3 x = 2112/35.315 x = 59.80 m^3 Step 3 Find the Carbon Monoxide. 1 m^3 = 43 micrograms Carbon Monoxide. 59.80 m^3 = x x = 2571.60 micrograms. Step 4 Convert Micrograms into grams. 1 gram = 1*10^6 micrograms. x gram = 2571.60 micrograms. x = 2.5716 * 10^-3 grams.
