Elements x and y form 2 binary compounds. In the first 14.0 g of x combines with 3.0 g of y. In the second, 7.00 g of x combine
Roman55 [17]

second compound

Let molar mass of x is = X

Let molar mass of y is = Y

Moles of x in second compound = Mass / molar mass = 7 / X

Moles of y in second compound = Mass / molar mass = 4.5 / Y

For second compound  

7 / X : 4.5/ Y = 1:1

Therefore

X / Y = 7/4.5

Y / X = 4.5/ 7

The mass of x in first compound = 14g

moles of x in first compound = 14/X

Mass of y in first compound = 3

moles of y in first compound = 3 / Y

14 / X : 3/ Y = 14Y / 3X = 14 X 4.5 / 3 X 7 = 3 :1

Thus molar ratio in first compound = moles of x / Moles of y = 3:2

Formula = x3y

Calculate the molar mass of K3PO4
julia-pushkina [17]

Answer:

Molar mass of K₃PO₄  = 212.27 g/m

Explanation:

K₃PO₄ (Potassium phosphate)

This is a ionic salt compounded of phosphate and potassium

Mass of potassium = 39.10 g/m

Mass of phosphorus = 30.97 g/m

Mass of oxygen = 16 g/m

Molar mass of K₃PO₄  = 39.10 x3 + 30.97 + 16 x4 = 212.27 g/m

Which types of substances dissolve better in water: hydrophobic or hydrophilic substances? why do you think so?
Alexxx [7]
Hydrophilic substances will dissolve better in water than hydrophobic substances. A substance that is hydrophilic is water loving or easily dissolved in water. Molecules of these substances form ionic bonds with the water molecules. Hydrophilic substances include alcohols. Hydrophobic substances repel water and do not mix.
