A student needs to prepare 250 mL of a 0.550 M aqueous solution of sucrose, C 12 H 22 O 11 ( aq ) , which is used frequently in
Grace [21]

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.

What is the engineering cycle and why is it important
Sauron [17]
An engineering cycle is meant to assess the environmental impacts in relation to economic impacts on a product. The assessment is  the whole life cycle of a product consisting of production, use phase and end of life. It's important because it helps mold the standard of living for generations to come and be sustained indefinitely. It protects against negative environmental factors but also reduces the cost of production for business', also.
