If Dr. I.M. Smart mixes 50ml of a 20% acid in water solution with 30ml of acid, what is the quantity and concentration of the fi nal solution?
2 answers:
Answer:
80ml of the solution with a 50% acid concentration.
Step-by-step explanation:
Amount of acid in the water solution:
50ml * 20%= 10 ml
∴There is 10ml of acid in the solution.
Final amount of liquid:
50ml + 30ml = 80ml
Final amount of Acid:
10ml + 30ml = 40 ml
Concentration of Acid in Solution
40ml / 80ml = 0.5 = 50%
50 ml * 20% = 10 ml 50+30 =80 10+30 =40 40/80=50%

Step-by-step explanation:
750,000,000 times 10^5 can be expressed as 7.5 times
7.55 times 10^13 is greater than 7.5 times 10^11.
The product is the result of multiplication. the product of a number and 48 --- 48x ---is (means equals) - 18 so its gonna be: 48x = -18 x = -18/48 x = - 3/8 <== ur number
Answer:

Step-by-step explanation :
a4 = 12--- > put the formula in it
2 × 4 + 4 = 1 2
a5 = 1 4 --- > 2 × 5 + 4 = 1 4
a6 = 1 6 --- > 2 × 6 + 4 = 1 6
