Is rubbing alcohol a mixture or solution?
It's a solution... but solutions are mixtures.
What are glucose test results?
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.
A chemist is making a solution that is to be 55 chlorine He has one solution that is 40 chlorine and another that is 65 chlorine He wants 100 liters of the final solution How much of each should?
Each should be 70
Is 70 percent Isopropyl rubbing alcohol a heterogeneous?
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.
A chemist needs 4 liters of a 50 percent salt solution All she has available is a 20 percent salt solution and a 70 percent salt solution How much of each of the two solutions should she mix to obtain?
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
How many liters of 10 percent alcohol solution must be mixed with 70 liters of a 70 percent solution to get a 30 percent solution?

What percentage of 200 is 70?
The answer is 35%. Solution: 70/200x100 =0.35x100 =35%
If you have a 70 percent solution of dextrose How many grams of dextrose is in 400ml of this solution?
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.
If you have a 70 solution of dextrose 1000ml. how many kg of dextrose is in 400 ml of this solution?

How many gallons of a 80 percent solution must mix with 70 gallons of 10 percent solution to get 70 percent solution?
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
What is 73 rounded off to the nearest tens and solution?
70
How many gallons of a 80 percent antifreeze solution must be mixed with 70 gallons of 20 percent antifreeze to get a mixture that is 70 percent antifreeze?
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.
How do you simplify -33v 70-7v to solve for v?
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
What does it mean if saturation level is 70 percent?
example: say saturation level of sugar in water is 70 percent, if the solution is 70 percent sugar, it is saturated
What is 72 percent of 70?
Basic maths - 10% is 7.2 multiply that by 7 and you get 50.4 - all without the aid of a calculator !
