Determine the volume of fluid in the graduated cylinder shown.

Sladkaya [172]

Answer:

22.5 mL

Explanation:

We are given an amount of a fluid in a graduated cylinder and required to determine its volume.

Liquids always take the shape of the container they are placed in. In the graduated cylinder shown, note how the top of the fluid curves downwards. The volume of the liquid is usually determined at the bottom of this curve or what is called the meniscus.

The bottom of the meniscus is at the 22.5 mL level and thus the volume of the fluid is 22.5 mL

What is an ethical vacuum?

Alenkasestr [34]

Moral relativism considers that something, such as abortion, can only be right or wrong in relation to one or another moral framework. Morality is then a human invention. The relevant moral principles are thus nothing but conventions that result from a process of tacit moral bargaining through which some groups can exert pressure on others in an effort to change the current moral conventions. This encourages the view that "anything goes" and that morality is just a matter of opinion. Relativism makes dialogue pointless, assuming that there is no binding truth or that partners in the dialogue are saying the same thing in different ways.

Bismuth oxide reacts with carbon to form bismuth metal: Bi2O3(s) + 3C(s) → 2Bi(s) + 3CO(g) When 775 g of Bi2O3 reacts with exces

goldfiish [28.3K]

Answer:

(a) 3.33 mol Bi

(b) 140. g CO

Explanation:

Step 1: Convert 775g to moles

Bi Molar Mass - 208.98 g/mol × 2 = 417.98 g/mol

O Molar Mass - 16.00 g/mol × 3 = 48.00 g/mol

775g Bi₂O₃ ÷ 465.98 g/mol = 1.66316 mol Bi₂O₃

Step 2: Find the conversion from Bi₂O₃ to Bi

1 mole of Bi₂O₃ equals 2 moles of Bi

Step 3: Use Dimensional Analysis

1.66316 mol · $\frac{2 \hspace{2} mol \hspace{2} Bi}{1 \hspace{2} mol \hspace{2} Bi_2O_3}$ = 3.32632 mol Bi

3.32632 mol Bi ≈ 3.33 mol Bi (3 significant figures)

Step 4: Find the conversion from Bi₂O₃ to CO

1 mole of Bi₂O₃ equals 3 moles of CO

Step 5: Use Dimensional Analysis

1.66316 mol · $\frac{3 \hspace{2} mol \hspace{2} CO}{1 \hspace{2} mol \hspace{2} Bi_2O_3}$ = 4.98948 mol CO

Step 6: Find molar mass of CO and convert moles to grams

C - 12.01 g/mol

O - 16.00 g/mol

4.98948 mol CO · 28.01 g/mol = 139.775 g CO

139.775 g CO ≈ 140. g CO (3 significant figures)
