Answer: 20 Square units
Explanation: A= b x h = 4 x 5 = 20
1/5 is 2% or 0.2, therefor 2/5 is 4% or 0.4
Answer:
4.732 grams
Step-by-step explanation:
2 US fluid ounces is exactly 59.147059125 mL of volume. 8% of that volume is 4.73176473 mL.
For a solution of this type, where 1 g/100 mL is considered a 1% solution this is the number of grams of solute needed.
About 4.732 grams of solute are needed to prepare 2 fl oz of 8% solution.
_____
We have assumed that 1 gram of solute gives you 1 gram of iodine. Depending on the exact solute used, that may or may not be the case.
Decimals are by 10.
50 x 2 is 100
that means that all you have to do is multiply the numerator by 2 and divide it by 100
23 x 2 is 46
(since the numerator is not larger than the denominator, you put a decimal at the beginning)
the answer is .46
