Answer 1

Answer #1

Given concentration is 9 ppm.

To convert ppm to percentage, divide the ppm value by 10,000.

$\small \therefore Percentage=\frac{9}{10000}$

$\small \boldsymbol{\therefore Percentage=0.0009\%}$

3. Carbon Monoxide (CO) is a colourless and odourless gas. Even at low levels of exposure, carbon monoxide can cause serious health problems. A home is considered safe if the mean CO concentration is 5.2 parts per million (ppm) or lower. We take a random sample of 8 readings in various locations of a home. These readings have a mean of 5.4 ppm and a standard deviation of 0.35 ppm. We would like to conduct a hypothesis test at the...

Recently, I measured the carbon monoxide (CO) mixing ratio out on the street in front of An-Najah as 42 ppm (during "rush" hour). If the ambient temperature and pressure were 22.3°C and 700.7mmHg: 1) What is the equivalent concentration in ug/m3? 2)Assuming my lungs absorbed all of the CO I inhaled (~6 Lpm) during the 60 minutes I was out there, what total mass of CO was in my blood stream?

Many studies have been conducted to determine the concentration of CO (carbon monoxide) near freeways with various conditions of traffic flow. The basic technique involves measuring CO concentrattions with a spectrophotometer. These machines are quite delicate and have to be calibrated every day. If the machine reads close to 70 ppm on the span gas, it’s ready for use; if not, it has to be adjusted. Each data set below represents some readings on span gas. Assume the Gaussian model,...

8. Carbon monoxide (CO) is a colorless, odorless, and deadly gas. Carbon monoxide is deadly for a multitude of reasons. One reason is that it binds to Complex IV in the electron transport chain of mitochondria. By binding to Complex IV, CO prevents the complex from binding to oxygen and transmitting electrons to oxygen. a. What will happen to the electron transport chain if it can no longer pass electrons along to oxygen? (2 points) b. What will happen to...
