What are the metric units of density

Answer : The unit of density are,

Explanation :

The Metric System measured the things in meters, grams, liters, etc and adds prefixes like kilo, milli and centi to the count orders of the magnitude.

Density : It is defined as the mass of a substance contained per unit volume.

In metric system,  the unit of mass is gram (g) and the unit of volume is liter (L), milliliter (mL) and cubic centimeter . So, the unit of density will be:

Formula used :

Thus, the unit of density are,

a. a primary source combines several different accounts of an event. b. a primary source generally benefits from having been written after an event.

explanation:

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.
