Molarity is measured in moles per Liter. If there are 1.35 g/mL, find out how many grams there are in a liter of solution.
If there are 1000 mL in one liter, we can multiply by 1000 to get g/L
1.35 g/mL x 1 Liter/1000 mL = 1350 g per Liter of solution
By weight, the NaOH is 33% or .33
1350 g x .33 = 445.5 g of NaOH
Molar mass of NaOH is 39.997 g
445.5 g x 1 mol NaOH/39.997 g = 11.13833538 moles per Liter
Rounded to significant figures, the answer is 11 mol/L NaOH
Is there suppose to be a picture or no?
Answer:
Examples of storage polysaccharides - <u>starch and glycogen</u> and structural polysaccharides - <u>cellulose and chitin</u>
Explanation:
Polysaccharides are the complex carbohydrate polymers, composed of monosaccharide units that are joined together by glycosidic bond.
In other words, polysaccharides are the carbohydrate molecules that give monosaccharides or oligosaccharides on hydrolysis.
The examples of storage polysaccharides are starch and glycogen. The examples of structural polysaccharides are cellulose and chitin.
Following are the pair of elements that result in an ionic compound
Option A and B
<u>Explanation:</u>
- Ionic compounds are defined as the compound that consists of ions held by two atoms of differently charged ions.
- These compounds have a positive charge of ions called cations and a negatively charged element is anions.
- In the above options, we shall say that the atoms such as Ca and K both result in cations as they release an electron to become a positive ion.
- Also, Cl and S both result in anions as they attract more electron to form negative ions.
- These positive and negative ion together results in an ionic compound.
This answer is C hope this helped
