How many moles of xenon trioxide are present in 1. 69 grams of this compound.
Vadim26 [7]

Answer:

0.00944

Explanation:

Xenon mass number on the periodic table: 131.29

Oxygen mass number: 16.00

Add them to find the molar mass of xenon trioxide: 131.29+3(16) = 179.29g/mol

Convert this to moles

1.69g * \frac{mol}{179.29g} = 0.00944mol

Density of the vinegar is higher than the density of the oil.

Explanation:

Density of the vinegar is higher than the density of the oil. The consequence of this is that the oil will be the top layer in the pitcher while the vinegar is at the bottom layer in the pitcher.

When mixing oil and vinegar will not produce a mixture because the oil contains non-polar molecules while vinegar is a solution of acetic acid in water and both of them are polar molecules.
