Answer:

The answer to your question is 0.10 M

Explanation:

Data

Molarity = ?

mass of Sucrose = 125 g

volume = 3.5 l

Formula

Molarity = moles / volume

Process

1.- Calculate the molar mass of sucrose

C₁₂H₂₂O₁₁ = (12 x 12) + (1 x 22) + (16 x 11)

               = 144 + 22 + 176

               = 342 g

2.- Convert the mass of sucrose to moles

                  342 g of sucrose ------------------- 1 mol

                  125 g of sucrose -------------------- x

                           x = (125 x 1) / 342

                           x = 0.365 moles

3.- Calculate the molarity

Molarity = 0.365 / 3.5

4.- Result

Molarity = 0.10

Why would defective collagen proteins affect an individuals joints?
umka21 [38]

Answer:

Defective collagen proteins affect an individuals joints, as <u>collagen is an important component protein in body</u><u> connective tissues</u>

Explanation:

Collagen is a crucial protein in the extracellular matrix of various connective tissues in body (tendons, ligaments, muscles). It constitutes major protein component in mammals body.

Collagen Vascular disease is a group of diseases affecting 'collagen' connecting tissue. Apart from inheritance, they can con occur due to autoimmune disease. This implies that body's immune system fights against itself & mistakenly damages its own tissues. So, these diseases have a huge bearing on body joints components. Eg : Lupus , Arthritis are common collagen vascular diseases. Arthritis mostly affects adults above 30 years of age, lupus can be diagnosed in younger people above 15 years of age also.

What mass of cucl2 is contained in 75.85 g of a 22.4% by mass solution of cucl2 in water?
Sindrei [870]
First  step: convert   22.4%  into   fraction
 that  is  22.4/100  which  is equivalent  to 0.224
  The  mass  of Cucl2  contained  in  75.85  of  22.4%  by  mass  of   solution  of  CUcl2 in  water is   therefore,
0.224 x75.85=16.99g
alternatively
75.85 --->100%
      ?        22.4%
by cross  multiplication =(22.4 x 75.85)/100 =16.99g
