Mei has 60 milliliters of a solution that is​ 35% nitric acid. How many milliliters of nitric acid does the solution​ contain?
(answer this and show your work please)
The solution contains _answer here_ milliliters of nitric acid.

Answers

Answer 1

Answer:

21ml

Step-by-step explanation:

60ml. 35% acid. What is 35% of 60 ml?

÷10 to find 10%

60÷10=6

6=10%

But this is no use

because you cannot multiply 10%to get 35%

(35% is not a multiple of 10)

So we try...

10%÷2=5%

So ÷2 to find 5%

6÷2=3

So 3=5%

5%x7=35%

So, we do

3x7=21

So 35%=21

Answer 2

Answer:

21ml

The diameter of the Sun is about 1.4 × 10^6 km. The diameter of Mars is about 7000 km.

What is the approximate ratio of the diameter of the Sun to the diameter of Mars?
A. 5 × 10^-3
B. 5 × 10^2
C. 2 × 10^3
D. 2 × 10^2

Answers

Answer:

 C.)  2×10²

(Sun dia) / (Mars dia) = (1.4 x 10⁶ km) / (0.7 × 10⁴ km) = (1.4/0.7) × 10²

The ratio of diameters is about 2 × 10².

_____

The applicable rule of exponents is ...

 (a^b)/(a^c) = a^(b-c)

__

The diameter of Mars can be expressed several ways.

 7000 = 7×1000 = 0.7×10,000 = 0.7×10⁴
