Learn how to convert the number of grams of a molecule to the number of moles of the molecule with examples below. This type of conversion problem mainly arises when you are given (or must measure) the mass of a sample in grams and then need to work a ratio or balanced equation problem...
Understanding how the measure works and what it really means allows you to calculate it without using a specific parts per million calculator, but those are available too if you don’t want to work it out manually. If you’re a chemistry student or learning about science in general, it’s...

One of the common tasks you will have to perform as a budding scientist who is able to work with data is understanding the concept of an average. Often, you will encounter a sample of similar objects that differ according to a single characteristic you are studying, such as mass. ...
Moles living inyour lawncan lead to dead plants, mounds of piled soil and damage to the grass. These small creatures are not rodents but are as pesky as them. They feed on grubs, worms and other lawn insects. Maintaining a pest-free lawn will discourage moles from returning, but contrary...
Atoms are extremely small particles, so they don’t suggest meaningful measurement. So, in order to work with meaningful amounts of substances, one requires grouping them into units dubbed moles. As mentioned above, a mole is the number of carbon atoms in twelve grams of the isotope carbon-...
Aluminum alloys play an important role in circular metallurgy due to their good recyclability and 95% energy gain when made from scrap. Their low density and high strength translate linearly to lower greenhouse gas emissions in transportation, and their
Of the remaining mass that makes up the four earth systems, the hydrosphere is a little more than 18%, the atmosphere less than 1%, and the biosphere a tiny 0.00008%. Note just how much greater the amount of mass is in the air, which we tend to think of as being ...
moles (nothing to speak of, just precautionary) when I showed her a couple of spots on my face that weren’t there before. Melanoma runs in my family, so I am particularly cautious about any new mark that has shown up. So I showed her my areas of concern and got the following ...
Do Gopher Baskets Work for Other Pests? Absolutely! Gopher basket wire is threaded together just close enough to let roots grow but small enough to keep out many pesky paw sizes including: Voles Prairie dogs Groundhogs Moles Squirrels Muskrats ...
