44.2124+0.81+7.335 significant digits
zhenek [66]

52  

Explanation:

We need to understand and apply the rules of significant figures when carrying out addition operations to solve this problem:

Rules of significant figures:

  • Non-zero digits are always significant in a given number
  • Any zeros between two significant digits are significant.
  • A final zero or trailing zeros in the decimal portion is significant.
  • Any leading zero in a decimal is significant.

In addition, the answer of the sum is given to the least number of significant digits of the given numbers:

 

        44.2124

    +    0.81

    +    7.335

sum  52.3574          

Now the least number of significant figure is 2 as seen in 0.81

we round the sum up to 52

2. (Exercise 4.1.6) A liquid adhesive consists of a polymer dissolved in a solvent. The amount of polymer in the solution is imp
Lilit [14]

Answer:

800 lb of pure solvent , 1700 lb of 20% solution and 500 lb of 10% solution will be mixed to form 3000 lb of 13 % solution .

Explanation:

3000 lb of 13% solution is required .

Total adhesive in weight = 3000 x .13 = 390 lb of adhesive

Available = 500 lb of 10% solution = 50 lb of adhesive

Rest = 390 - 50 = 340 lb required .

rest mass of solution = 3000 - 500 = 2500 lb

mass of adhesive required = 340 lb

Let the mass  of 20% required be V

mass of adhesive = .20 V

.20 V = 340

V = 1700

rest of the volume = 2500 - 1700 = 800 lb which will be of pure solvent

So 800 lb of pure solvent , 1700 lb of 20% solution and 500 lb of 10% solution will be mixed to form 3000 lb of 13 % solution .
