PSYCHO15rus [73]

Answer:

The answer to your question is 43.8 mL of acid.

Step-by-step explanation:

Data

Total volume = 362 ml

12.1 % is acid

The Volume of acid = ?

Process

1.- Use the rule of three and cross multiplication to solve this problem.

               362 ml ------------------- 100%

                    x       -------------------  12.1 %

                    x = (12.1 x 362) / 100

                    x = 4380.2 / 100

                    x = 43.802 ml

2.- Round your answer to the nearest tenth.

                        43.802   only consider the first decimal

                        43.8 mL

3.- Conclusion

    A 12.1% solution of acid has 43.8 mL of acid.

<h3>What is scientific notation?</h3>

Scientific notation is simply a way of expressing numbers that are too large or small to be written in decimal form.

It may be referred to as standard index form or scientific form.

From the information given, we have;

a. 0. 000003 is written in standard form as;

= 3 × 10^-6 × 3 × 10^6

= 3 × 10^-6 + 3

= 3 × 10^0

= 3

b. 56, 000, 000. 00 is written in standard form as;

= 5. 6 × 10^7 × 6 × 10^-7

= 33. 6 × 10^7 -7

= 33. 6 × 10^0

= 33. 6

c. 8. 0 × 10^-3 × 7. 2 × 10^5

= 57. 6 × 10^-3 + 5

= 57. 6 × 10^2

d. 4. 0 × 10^-3 × 4. 0 × 10^-4

= 4. 0 ^ -3 +(-4)

= 4. 0 × 10^-7

e. 7. 0 × 10^3 × 7. 0 × 10^4

= 7. 0 × 10^ 3-4

= 7. 0 × 10^-1

Thus, scientific notation is also referred to as standard form.
