A bottle of coke is 250.0 mL. What is the volume in cubic centimeters?
hoa [83]

Answer:

The volume in cubic centimeters is 250

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

So:

x=\frac{c*b}{a}

The direct rule of three is the rule applied in this case where there is a change of units. To perform this conversion of units, you must first know that 1 mL = 1 cubic centimeters. So, if 1 cubic centimeters is 1 mL, how many cubic centimeters equals 250 mL?

cubic centimeters=\frac{250 mL*1 cubic centimeters }{1 mL}

cubic centimeters= 250

<u><em>The volume in cubic centimeters is 250</em></u>

How many moles of hydrogen atoms are there in one mole of C6H12O2
zvonat [6]

In 1 molecule of the compound C₆H₁₂O₂ there are 12 moles of hydrogen atoms

<h3>Further explanation</h3>

Given

C₆H₁₂O₂ compound

Required

moles of Hydrogen

Solution

In a compound, there is a mole ratio of the constituent elements.

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

In the C₆H₁₂O₂ compound, there are 3 forming elements: C, H and O

The number of each element is indicated by its subscript

C: 6 moles

H = 12 moles

O = 2 moles

Bismuth oxide reacts with carbon to form bismuth metal:
kvv77 [185]

(a) 3.33 mol Bi

Explanation:

Step 1: Convert 283 g 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

283 g Bi₂O₃ ÷ 465.98 g/mol = 0.0607 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  ·   = 3.32632 mol Bi

3.32632 mol Bi ≈ 3.33 mol Bi

What is bismuth oxide used for?

Bismuth oxides have been considered as an interesting material because of their dielectric properties and have been used for applications such as optical coatings, metal-insulator-semiconductor capacitors and microwave-integrated circuits.

What is bismuth used for in everyday life?

Bismuth finds its main uses in pharmaceuticals, atomic fire alarms and sprinkler systems, solders and other alloys and pigments for cosmetics, glass and ceramics. It is also used as a catalyst in rubber production
