Carbon's molar mass is 12gm
Oxygen's molar mass is 16gm
So CO2 molar mass is 44gm
Hence 1mol of CO2 contains 44gm
There 1/4mol of CO2 contains 44/4=11gm.
Hope it helps
It is definitely a molecule
<u>Explanation:</u>
The number of moles that are present in a liter of a solution is called Molarity. Mole is the unit of Molarity.The concentration of the solutes that are present in a solution refers to Osmolarity . The unit is osmol. This helps in observing the movement of water from one side to another side of a semipermeable membrane.
The main property of salts that helps to understand the differentiation between the molarity and osmolarity is the salts Ionization. One mole Na+ and one mole of Cl- is produced by the dissociation of a mole of sodium chloride occurs. The diffusion of water is the osmosis. Here, the one molar sodium chloride solution produces a osmotic pressure which is high than one molar glucose solution and this will not undergo dissociation.
Answer:
Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
