What is the formula for C2Se4?
The name of C2Se4 is carbon diselenide, more often written as CSe2.It is a yellow-orange oily liquid with very potent putric or pungent odor (treshold < 1 ppb).
50 parts per billion' means what?
Imagine cube of air 1 meter by 1 meter by one meter. There are 5 BBs in the cube. They will fill up about 50 parts per billion (ppb) of the cube's volume. There are about 7 billion people living on Earth. 350 people, about a typical Facebook friends list, represent 50 ppb of the total population of the world.
How do convert Kevin into Celsius?
Use this equation to convert Kelvin to degrees Celsius/Centigrade: [°C] = [K] - 273.15
Can you convert temperature?
Fahrenheit: ___°C*1.8+32 Kelvin: ___°C+273.15
Photosynthesis is a process in which green plants convert to what?
Actually, the green plants don't convert TO anything in photosynthesis. Rather, they convert the light energy given off by sun light into glucose (energy).
How do you get from parts per billion into a percent?
The conversion factor is 10 million. To convert to ppb to percent, you divide by 10 million.The conversion factor is 10 million. To convert to ppb to percent, you divide by 10 million.The conversion factor is 10 million. To convert to ppb to percent, you divide by 10 million.The conversion factor is 10 million. To convert to ppb to percent, you divide by 10 million.
How to convert ppb into microliter?
Parts per billion (ppb) is a unit of concentration, while microliter (μL) is a unit of volume. To convert ppb to microliters, you need to know the density of the substance in question. The formula for this conversion is: microliters = (ppb * volume in liters) / density in g/mL. This formula takes into account the concentration of the substance in ppb and its density to give you the volume in microliters.
How do you convert percent transmittance to mgL?
how do you convert percent transmittance to mg/l
What is 28 ppb equal to in ppm?
To convert parts per billion (ppb) to parts per million (ppm), you divide by 1000. So, 28 ppb is equal to 0.028 ppm.
How do you convert 49 tonnes to ppb?
Without more information you cannot.
How do you convert microgram per meter-cubed to ppb?
Ppb means parts per billion. When you are talking about weight per volume, a gram is deemed equivalent to a millilitre. Micrograms per metre cubed means micrograms per 1000 litres. You will have to divide by 1000 to convert to micrograms per litre, giving you ppb.
How do you convert parts per billion to parts per million?
1000 ppm = 1 ppb I think equation to convert ppm to ppb is: 1 ppm = 1000 ppb, or 1 ppb = 1/1000 ppm * * * * * Wrong way around, I am afraid. 1000 parts per billion is 1 ppm. To convert ppb to ppm divide by 1000.
A 250.0 ml sample of tap water is found to contain 6.000 microgram of arsenic What is the concentration of arsenic in ppb?
To find the concentration of arsenic in ppb, we need to convert micrograms to grams and then calculate the concentration. First, convert 6.000 micrograms to grams by dividing by 1,000,000. This gives you 0.000006 grams of arsenic. Then, calculate the concentration by dividing the mass of arsenic by the volume of water (in liters) and multiplying by 1 billion to convert to ppb. The concentration of arsenic in the tap water sample is 24 ppb.
How do you convert nanograms per gram to parts per billion?
To convert nanograms per gram (ng/g) to parts per billion (ppb), you can use the fact that 1 ng/g is equivalent to 1 ppb. Since 1 gram is equal to 1 billion (1,000,000,000) nanograms, the conversion is direct: simply state the value in ng/g as the same numerical value in ppb. For example, 10 ng/g is equal to 10 ppb.
What is the ppb by weight of zinc in the human body?
4.518514 ppb
What is the composition of the atmosphere on Mars?
