No, just neutral ph.
It's a solution... but solutions are mixtures.
Glucose test results indicate the amount of sugar (glucose) in the blood. Normal fasting glucose levels are typically between 70-100 mg/dL. Elevated levels may indicate diabetes or pre-diabetes, while low levels may indicate hypoglycemia.
Each should be 70
No, 70% isopropyl rubbing alcohol is a homogeneous mixture because it is a uniform solution of isopropyl alcohol with water. It has the same composition throughout and its components are evenly distributed.
You will need more data about all densities (in kg/Litre)and you must be sure of using mass% = (g solute)/(100 g solution)Solve two equations for both X and Y:4*d50*50 = X*d20*20 + Y*d70*70 (based on salt mass balance in diff. sol'n.)4*d50 = X*d20 + Y*d70 (based on solutions mass balance)In which:dm = density of the 'm'% salt solution in kg/Litre)X and Y = volume of the 20% and 70% salt solutions respectively

The answer is 35%. Solution: 70/200x100 =0.35x100 =35%
In a 70% dextrose solution, 70% of the total weight is dextrose. To calculate the grams of dextrose in 400ml of this solution, you would multiply 400ml by 70% (or 0.70) to find the amount of dextrose present.

420 gallons. Here's how to find it; If X = Gallons of 80% mix, 0.8*X + 0.1*70 = 0.7*(X+70) Which we can then solve, 0.8X + 7 = 0.7X + 49 0.1X = 42 X = 420

70 gallons of 20% solution contains 70*0.2 = 14 gallons of antifreeze. Suppose you need G gallons of the 80% antifreeze solution. This will contain 0.8*G gallons of antifreeze. Total volume of solution = G + 70 gallons Volume of antifreeze required in this solutions to make it a 70% solution is 0.7*(G + 70) = 0.7G + 49 gallons. Volume of antifreeze = 14 + 0.8G gallons So 0.7G + 49 = 14 + 0.8G 0.7G + 35 = 0.8G 35 = 0.1G 350 = G Answer: 350 gallons.
If you mean: -33v = 70-7v then v = 70/-26 Otherwise not knowing the plus, minus or equal value of 70 it has no solution
example: say saturation level of sugar in water is 70 percent, if the solution is 70 percent sugar, it is saturated
Basic maths - 10% is 7.2 multiply that by 7 and you get 50.4 - all without the aid of a calculator !
