what mass of nitrogen is needed to fill an 855 l tank at stp?
Mass Computer
This is a basic mass figurer based on density and volume. This figurer takes and generates results of many common units.
What is mass?
Mass is typically defined every bit the amount of matter within an object. It is near commonly measured every bit inertial mass, involving an object's resistance to dispatch given some net forcefulness. Matter, however, is somewhat loosely defined in scientific discipline, and cannot exist precisely measured. In classical physics, matter is whatever substance that has mass and volume.
The amount of mass that an object has is oftentimes correlated with its size, but objects with larger volumes do not e'er accept more than mass. An inflated airship, for example, would take significantly less mass than a golf ball made of silver. While many different units are used to describe mass throughout the world, the standard unit of measurement of mass under the International System of Units (SI) is the kilogram (kg).
There exist other common definitions of mass including active gravitational mass and passive gravitational mass. Agile gravitational mass is the mensurate of how much gravitational force an object exerts, while passive gravitational mass is the measure of the gravitational force exerted on an object inside a known gravitational field. While these are conceptually distinct, there have non been conclusive, unambiguous experiments that take demonstrated meaning differences betwixt gravitational and inertial mass.
Mass vs. Weight
The words of mass and weight are frequently used interchangeably, but even though mass is often expressed by measuring the weight of an object using a spring scale, they are not equivalent. The mass of an object remains constant regardless of where the object is and is, therefore, an intrinsic property of an object. Weight, on the other hand, changes based on gravity, as information technology is a measure of an object's resistance to its natural country of freefall. The force of gravity on the moon, for instance, is approximately one-6th that on world, due to its smaller mass. This ways that a person with a mass of 70 kg on earth would weigh approximately one-sixth of their weight on earth while on the moon. Their mass, nonetheless, would yet be seventy kg on the moon. This is in accord with the equation:
In the equation above, F is force, G is the gravitational constant, chiliad1 and 10002 are the mass of the moon and the object it is acting upon, and r is the moon'southward radius. In circumstances where the gravitational field is constant, the weight of an object is proportional to its mass, and there is no issue with using the same units to express both.
In the metric system, weight is measured in Newtons post-obit the equation W = mg, where W is weight, m is mass, and g is the acceleration due to the gravitational field. On earth, this value is approximately 9.8 m/sii. It is important to note that regardless of how strong a gravitational field may be, an object that is in gratuitous fall is weightless. In cases where objects undergo acceleration through other forces (such as a centrifuge), weight is adamant by multiplying the object's mass past the total acceleration away from complimentary fall (known as proper acceleration).
While mass is defined by F = ma, in situations where density and volume of the object are known, mass is besides commonly calculated using the following equation, as in the calculator provided:
g = ρ × V
In the above equation, m is mass, ρ is density, and V is volume. The SI unit of measurement for density is kilogram per cubic meter, or kg/m3 , while volume is expressed in m3 , and mass in kg. This is a rearrangement of the density equation. Farther details are available on the density computer.
