Answer:
There are 342 g/ 95. 2 g/m = 3.59 moles
Explanation:
MgCl2 → Molar mass is 95.2g g/m
This is the mass in one mol so to find out the moles in 342g we have to divide the mass between the molar mass.
342 g/ 95. 2 g/m = 3.59 moles
Answer:
Yah, it's true.
because protons are represented as helium (²4He) which are positive.
electrons are represented as 0-1e which is negative
Total density of filled ball with oxygen gas:
The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d). The ball filled with hydrogen will float in the air because total density of filled ball is lessor than the density of an air. Density of the evacuated ball D = 0.214 g/L
Density of oxygen gas =
Mass of the oxygen gas :

Positive ion with a radius smaller than the radius of the atom
The equator will be least affected since it's orientation and distance to the sun changes the least from season to season.
