{'different densities px': [0, 0, 0, 1], 'miscible liquids': [0, 0, 0, 1], 'mixture': [0, 0, 1, 5], 'density': [2, 0, 1, 3], 'same volume': [0, 0, 0, 1], 'p2': [0, 1, 0, 2]}

When two miscible liquids (liquids that can mix together in any proportion) of the same volume but different densities are mixed, the density of the mixture can be calculated using the formula:

Density of mixture = (Density of liquid 1 x Volume of liquid 1 + Density of liquid 2 x Volume of liquid 2) / (Volume of liquid 1 + Volume of liquid 2)

In this case, since both liquids have the same volume, the formula simplifies to:

Density of mixture = (Density of liquid 1 + Density of liquid 2) / 2

Therefore, the correct answer is option 1 - the density of the mixture is given by the average of the densities of the two liquids.
