Answer:

1.non electrolytes

2.electrolytes

3.non electrolytes

4.electrolytes

5.electrolytes

6.electrolytes

Explanation:

electrolytes are substance in their molten form which can be decomposed by the passage of electricity exay includes acids,base and salts etc were as non electrolytes cannot be decomposed by the passage of electricity example alcohol,sugar organic solvents etc. Electrolytes in the body like potassium, sodium in their molten form helps to keep the electrical circuitry of the heart well

0.500 mile of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (
SCORPION-xisa [38]

The correct question is as follows: 0.500 moles of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (plz help!)

Answer: The molarity of this solution is 0.25 M.

Explanation:

Molarity is the number of moles of a substance divided by volume in liter.

As it is given that there are 0.5 moles of potassium oxide in 2.00 L of water so, the molarity of this solution is calculated as follows.

Molarity = \frac{moles}{volume(in L)}\\= \frac{0.5 moles}{2.00 L}\\= 0.25 M

Thus, we can conclude that molarity of this solution is 0.25 M.

What is the molar mass of H2(SO4)3?​
nalin [4]

Answer:

Explanation:

The molecular mass of C2H6 is approximately 30 or [(2 x 12) + (6 x 1)]. Therefore the molecule is about 2.5 times as heavy as the 12C atom or about the same mass as the NO atom with a molecular mass of 30 or (14+16).
