Salt water with a density of 1.1 × 10 & sup 3; kg / M & sup 3; is needed for salt water seed selection

Salt water with a density of 1.1 × 10 & sup 3; kg / M & sup 3; is needed for salt water seed selection

500*1.1=550g
If not, 50g should be subtracted or diluted with 45.45ml water

10. The salt water with density of 1.1 × 10 kg / M is needed for salt water seed selection. The salt water with density of 0.05 M is prepared and its mass is 60 kg. Is this kind of salt water suitable for seed selection

60/0.05=1.2×10^3kg/m,
So it doesn't match

Before spring sowing, we need to use salt water with density of 1.1 × 103kg / m3 for seed selection? If not, add salt or water, how much?

(1) The density of the prepared sample: ρ sample = MV = 1.2kg1 × 10 − 3m3 = 1.2 × 103kg / m3, ∵ 1.2 × 103kg / m3 ＞ 1.1 × 103kg / m3, ∵ does not meet the requirements, water should be added; (2) set the amount of water to be added as △ mkg, because the density of water is 1.0 × 103kg / m3, so the volume of water to be added: △ v = △ m ρ water

The density of brine is 1.1 * 10kg / M06. If 0.05m06 brine is prepared, its mass is 60kg,
Do you meet the requirements? If not, add----

First calculate the density of brine, ρ = m / v = 60kg / 0.05m3 = 1.2 * 10 ^ 3kg / m3 ＞ 1.1x10 ^ 3kg / m3, so it does not meet the requirements. In order to reduce the density of brine, it is necessary to add less dense components in the mixture, so water should be added
