The concentration of carbon monoxide in an urban apartment is 49 µg/m3. What mass of carbon monoxide in grams is present in a room measuring 8 ✕ 12 ✕ 22 ft? (Enter your answer to three digits.)
Thank you for the opportunity to help you with your question!
total volume in m^3=8*12*22*0.3048*0.3048*0.3048
=so total CO mass=49*10^-6*59.8
Isnt 49 micrograms equal to 49*10^-5 and not 49*10^-6?
so 49micro grams=49*10^-6 grams
if you are still not sure please check with
Micro (symbol µ) is a unit prefix in the metric system denoting a factor of 10−6 (one millionth). Confirmed in 1960, the prefix comes from the Greek μικρός (mikrós), meaning "small". The symbol for the prefix comes from the Greek letter μ (mu).
