The molar mass of methane is 16.04 J/g-K. molarheatcapacity=(2.20Jg∗K)(16.04g1mol) Multiplying the above together you get: molarheatcapacity=35.3J/mol∗KHow Much Heat Is Required to Raise the Temperature of a Substance? In order to calculate how much heat is needed to raise the...
Hello there, I have a percent composition lab involving the percent of calcium carbonate in seashells and I would like some help in figuring out how i calculate that percentage. I've recorded mass of the seashell and the initial/final NaOH that i have used in the lab. My teacher gave us...
You may have a quantity of particles that do not constitute a mole. For example, your sample of hydrogen gas may weigh only 2.52 × 10-4 kg. You can use the atomic mass of hydrogen, measured in AMU, to calculate the fraction of a mole of the gas in your sample. Just divide the ...
To calculate the amount of chloride physically bound in C-A-S-H, one needs to determine the C-A-S-H content, which can be very challenging in blended cement systems without relying on complex hypotheses (e.g., the amount of water in the C-A-S-H, the incorporation of guest ions, ...
When calculating the sand's weight, make sure you do not confuse the tonne (metric ton) with the ton (short ton). The first one is used by all countries in the world and is defined to be equal to 1000 kg by the international body of standardization. The ton is currently only used ...
Find the mass of sodium formate that must be dissolved in 150.0 cm^3 of a 0.50 M solution of formic acid to prepare a buffer solution with pH = 3.10. To prepare a 15% solution in 75 ml distilled water, how much of sodium chloride...
