Saline solution a is 10% strength and saline solution b is 5% strength. i have an order for 6 litres of an 8% saline solution. to fill the order how many litres of solution a should be diluted with solution b? (hint. assume a 1% solution contains r grams of salt per litre.)

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
