A 25.0 ml sample of a saturated c a ( o h ) 2 solution is titrated with 0.022 m h c l , and the equivalence point is reached after 36.4 ml of titrant are dispensed. based on this data, what is the concentration (m) of c a ( o h ) 2 ?
The concentration of the 25 mL Ca(OH)₂ solution needed to reach the equivalence point with 36.4 mL 0.022 M HCl solution is 0.016 M
Balanced equation2HCl + Ca(OH)₂ —> CaCl₂ + 2H₂O
From the balanced equation above,
The mole ratio of the acid, HCl (nA) = 2The mole ratio of the base, Ca(OH)₂ (nB) = 1How to determine the concentration of Ca(OH)₂ Concentration of acid, HCl (Ca) = 0.022 M Volume of acid, HCl (Va) = 36.4 mL Volume of base, Ca(OH)₂ (Vb) = 25 mLConcentration of base, Ca(OH)₂ (Mb) =?CaVa / CbVb = nA / nB
(0.022 ×36.4) / (Cb × 25) = 2
0.8008 / (Cb × 25) = 2
Cross multiply
Cb × 25 × 2 = 0.8008
Cb × 50 = 0.8008
Divide both side by 50
Cb = 0.8008 / 50
Cb = 0.016 M
Thus, the concentration of the Ca(OH)₂ solution is 0.016 M

Your question seems incomplete, the probable complete question is:
Sometimes guests brought their own knives and spoons, and sometimes they were furnished by the host. If not eating something soft or soupy that required a spoon, people ate with their fingers, using their knives only to take food from the main serving platter and to cut it when necessary. The knife was placed on the right side of the trencher, and the bread was on the left. Cups were not placed on the table. If a guest wanted a drink, he or she would ask a servant, who would bring them a cup that was kept on a side table or sometimes in a cool bath of water. When the guest finished drinking, they would return the cup to the servant, who would rinse it out, making it ready for the next guest.

Two triangles are similar if their corresponding angles are congruent and the corresponding sides are in proportion.
What are similar triangles?Your information is incomplete. Therefore, an overview of similar triangles will be given.
Similar triangles are the same shape, but not necessarily the same size. In this case, the triangles are congruent if, in addition to this, their corresponding sides are of equal length.
When all the three sides of a triangle are simply in proportion to the three sides of another triangle, then it can be stated that the two triangles are similar. Therefore, if AB/XY = BC/YZ = AC/XZ then ΔABC ~ΔXYZ.

Rj corporation has provided the following information about one of its inventory items: date transaction number of units cost per unit 1/1 beginning inventory 400 $ 3,200 6/6 purchase 800 $ 3,600 9/10 purchase 1,200 $ 4,000 11/15 purchase 800 $ 4,200 during the year, rj sold 3,000 units. What was ending inventory using the average cost flow assumption?
Using the Average cost flow assumption, the Ending Inventory would be $770,000.
What would be the ending inventory under average cost flow?Here the prices of all the goods will be an average value of their various prices.
The average price is therefore:
= Total cost of goods / Total number of units
= ((3,200 x 400) + (3,600 x 800) + (4,000 x 1,200) + (800 x 4,200)) / (400 + 800 + 1,200 + 800)
= 12,320,000/3,200
= $3,850
Ending inventory is therefore:
= (Goods purchased - Goods sold) x 3,850
= (3,200 - 3,000) x 3,850
= $770,000
