Answer:
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
Explanation:
You need to prepare 250. mL of a 0.550 M aqueous solution of sucrose, C12H22O11 (aq),
which is used frequently in biological experiments.
Based on your answer above, what is the value of x?
Solution:
A 0.550 M aqueous solution contains 0.550 mole of sucrose per liter of solution.
250 ml = 0.250 liter
Thus a 0.250 liter of a 0.550 M aqueous solution of sucrose contains 0.250 * 0.550 = 0.1375 mole of sucrose
Recall:
Mass = number of moles * mass of 1 mole
mass of 1 mole of C12H22O11
= 12(12) + 1(22) + 16(11)
= 144 + 22 + 176
= 342 grams
Mass = 0.1375 * 342 = 47.025 grams of sucrose.
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
Answer:
The soil property that is been observed is SOIL TEXTURE.
Explanation:
There are different types of soil and each one has its unique characteristics. The characteristics of soil include: texture, structure, porosity, chemistry and colour.
Soil texture refers to the property of the soil, which indicates the relative constituent of various particles of diverse sizes that are present in the soil. The soil textures determines the amount of air and water a soil can hold and influence the rate at which water pass through its particles. It also determines the ease with which the soil can be worked upon. Soil texture can be determined by rubbing the soil particles on one's fingers.
