where we could use the mass of carbon, mass of hydrogen, and mass of oxygen to parse out the percentage composition of each element in glucose. When we dissolve solids in water, we can use the chemical formula and the mass of
Carbon-14 dating works by comparing the ratio of carbon-12 to carbon-14 in a sample to that in a living organism, allowing for the determination of the age of formerly living things fairly precisely. The half-life of carbon-14 is 5,700 years, making it reliable for dating organic matter...
Find the relative mass of any atom by adding the number of protons to the number of neutrons. Hydrogen has a relative atomic mass of 1, and carbon-12 has a relative atomic mass of 12. Isotopes of the same element have different numbers of neutrons, so you need to calculate for one spe...
After the rover's arm scoops up the samples, a gas chromatograph, a mass spectrometer and a laser spectrometer will measure carbon-containing compounds and isotope ratios, which indicate the history of water on Mars. An Alpha Particle X-ray Spectrometer will measure the quantity of different ...
is this meteorite is easy to break into the moon, because there is almost no resistance, meteorite impact force is very big, hit ground surface cracked a big hole, the hot, liquid mass of molten rock from cracks in shock... Facing death of that a moment, human beings finally wake up,...
Some points to consider when selecting a location for aurora photography: Geographic Latitude: It would be ideal, although not necessary, to find a spot within the auroral belt. (According to Dr. Syun-Ichi Akasofu, this is the polar region where the aurora is visible about two-thirds of the...

The mass of a carbon atom is {eq}1.9927 \times 10^{-23} {/eq} g. How many carbon atoms are in a 12 gram diamond? Avogadro's Number: The mass of one atom of an element is equal to the average atomic mass of the element divided by Avogadro'...
Some of these isotopes, such as carbon-13, are stable, but some are unstable and decay over time to a more stable state. Such isotopes, such as carbon-14, are radioactive. Virtually all elements have more than one isotope, so each has an atomic mass that contains a decimal fraction. ...
Example: Find the atomic mass of an isotope of carbon that has 7neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons. The atomic mass of the atom is the mass of the protons plus the mass of the neutrons, 6 + 7, or ...
