You should put a 3. That way there are 6 H and 3 O on each side.
Answer:
Ether
Explanation:
NB: The boiling point of the liquids given are referred to as their normal boiling point i.e the boiling point at atmospheric pressure.
The relationship between normal Boiling point and vapor pressure is that; at a given temperature the lower the normal boiling point, the higher the vapor pressure.
hence ether with the least normal boiling point of 35°C is expected to have the largest vapor pressure near room temperature.
Valence electron/s - it's electron/s located in outer shell of an atom.
Fluorin have 7 valence electrons located in 2 shell.

Answer:
6.46×10²² formula units
Explanation:
From the question given above, the following data were obtained:
Mass of MgCl₂ = 10.2 g
Number of formula units =?
From Avogadro's hypothesis,
1 mole of MgCl₂ = 6.02×10²³ formula units
But,
1 mole of MgCl₂ = 24 + (35.5×2) = 24 + 71 = 95 g
Thus, we can say:
95 g of MgCl₂ = 6.02×10²³ formula units
Finally, we shall determine the formula units in 10.2 g MgCl₂. This can be obtained as follow:
95 g of MgCl₂ = 6.02×10²³ formula units
Therefore,
10.2 g of MgCl₂ = (10.2 × 6.02×10²³) / 95
10.2 g of MgCl₂ = 6.46×10²² formula units
Thus, 10.2 g of MgCl₂ contains 6.46×10²² formula units
