When selecting seeds with salt water, the density of salt water is 1.1 * 10 ^ 3kg / m ^ 3. Now 400ml salt water is prepared, and the mass is 0.6kg Does this salt water meet the requirements? If not, how much salt or water should be added?

Calculation ρ = m / v = 600g / 400ml = 1.5g/m & # > 1.1 * 10 ^ 3kg / m ^ 3, so it does not meet the requirements
To reduce its density, water should be added
