Answer:
Answer in explanation.
Explanation:
The mole is a unit for counting 6.02 1023 representative particles. The dozen is used to count 12 items.
Answer:
The answer to your question is 97 ml
Explanation:
Data
volume = ? ml
concentration = 1.01 M LiNO₃
mass = 6.63 g
Process
1.- Calculate the molecular weight of LiNO₃
LiNO₃ = (1 x 6.94) + (1 x 14) + (16 x 3)
= 6.94 + 14 + 48
= 69 g
2.- Calculate the moles of LiNO₃
69 g ------------------ 1 mol
6.63 g --------------- x
x = (6.63 x 1) / 69
x = 0.096 moles
3.- Calculate the volume
Molarity = moles / volume
-Solve for volume
Volume = Molarity x moles
-Substitution
Volume = 1.01 x 0.096
-Result
Volume = 0.097 l or 97 ml
Answer:
Lactose is found in animal milk is lactase is the enzyme that is required to digest it.
Explanation:
Lactose is a disaccharide made of glucose and galactose units. This sugar is naturally present in animal milk and it is digested (broken in its units) by the lactase enzyme.
Some people are lactose intolerant because their bodies is not able to produce the enzyme. If they ingest dairy products it may cause health issues. Nowadays it is possible to purchase the lactase enzyme and ingest it with a dairy food to avoid any health effects.
Glucose is a hexose monosaccharide. It is one of the three major monosaccharides along with fructose and galactose. These are carbohydrates with a general formula of Cₓ(H₂O)ₓ, where x could be any number.
Now, you don't have to know the structural formula of the glucose to answer this. Just account all the elements in the glucose. You know that there are 6 oxygen atoms all in all. One of them belongs to the single carbonyl group. Consequently, that would mean that the remaining 5 oxygen atoms bond with hydrogen atoms to form
5 OH groups.
Just to be sure let us refer to the structural formula of glucose shown in the picture. It indeed has 5 OH groups.
