The weight on the moon will be one-sixth that on the Earth, but the amount of mass is the same in both places. To weigh the Earth, we would need to know in which object's gravitational field we want to calculate the weight. The mass of the Earth, on the other hand, is a ...
From the slope one can then calculate the grain boundary diffusion coefficient when the volume diffusion coefficient in the grains is known or determined from the first part of the SIMS depth profile. However, surface roughness and the necessity to deposit a conductive layer on the surface of ...
For this reason, when you calculate your mass on a scale designed for use on Earth, weight is already factored into the operation of the scale. Mass is not weight, but they are always directly proportional to each other by the value of g, whatever it may be. But what does this mean ...
To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in...

What is the mass percent of nitrogen in ammonium carbonate, (NH_4)_2CO_3? In the compound PtCl2(NH3)2, what is the percentage of the mass due to nitrogen? Calculate the mass percent of nitrogen in (NH4)2SO4. What is the percent composition of nitrogen in (NH4...
Determining an amount of a substance can sometimes be very hard if there are no available information about the substance. Fortunately, the molar mass allows one to relate several quantities that describe the amount of a substance, whether it is an element or compound. The molar mass, or ...
It is possible to go as high as 16,000 feet (4,900 meters) without supplemental oxygen, giving the jumper up to 75 seconds of free fall. When the plane is lined up properly over the jump site, the skydivers jump out of the plane. At about 2,500 feet (760 meters), the skydiver...
Here is how to calculate how much water you should drink a day for both health and weight loss benefits. Your weight: The first step to knowing how much water to drink every day is to know your weight. The amount of water a person should drink varies on their weight, which makes sense...
To determine how much weight or body fat you want to lose: Calculate Your Ideal Weight: Use tools like the Body Mass Index (BMI) as a general guideline, but also consider factors like muscle mass and overall health. Aim for a range rather than a specific number to allow flexibility. ...
