Answer:

C3H8

Explanation:

Step 1:

Relevant details from the question are noted below:

Mass of the alkane is 1.17g

Volume (V) = 674 mL

Temperature (T) = 28°C

Pressure (P) = 741 mmHg.

Gas constant (R) = 0.08206 atm.L/Kmol

Step 2:

Convert to the appropriate units.

For Volume:

1000mL = 1L

So, 674mL = 674/1000 = 0.674L

For Temperature:

Temperature in Kelvin = Temperature in Celsius + 273

Temperature in Celsius = 28°C

Temperature in Kelvin = 28°C + 273 = 301K

For Pressure:

760mmHg = 1atm

So, 741 mmHg = 741/760 = 0.975atm

Step 3:

Calculate the moles of the alkane.

The moles of the alkane can be found using the ideal gas equation, presented below:

Volume (V) = 0.674L

Temperature (T) = 301K

Pressure (P) = 0.975atm

Gas constant (R) = 0.08206 atm.L/Kmol

Number of moles (n) =?

PV = nRT

n = PV /RT

n = (0.975 x 0.674)/(0.08206x301)

n = 0.0266 moles

Step 4:

Calculate the alkane’s molar mass.

Mass of alkane = 1.17g

Number of moles = 0.0266moles

Molar Mass =?

Number of moles = Mass/Molar Mass

Molar Mass = Mass/Number of moles

Molar Mass of alkane = 1.17/0.0266 = 44g/mol

Step 5:

Determine the molecular formula of the alkane.

This is based on:

The general formula for alkanes is CnH2n+2

To find the molecular formula, we start with n = 1, 2, 3, etc., until we find the molar mass of 44.

When n = 1

CnH2n+2 = CH4 = 12 + (4x1) = 16g/mol

When n = 2

CnH2n+2 = C2H6 = (12x2) + (6x1) = 30g/mol

When n = 3

CnH2n+2 = C3H8 = (12x3) + (8x1) = 44g/mol

It can be observed that for n equal to 3, the molar mass is 44g/mol.

Thus, the molecular formula of the alkane is C3H8.

The primary issue was declaring int prod within the while loop, which caused prod to reset to 1 each time the loop executed.

The term for the contents of the cell is an absolute cell reference. Excel allows each cell to contain numbers, strings, or formulas. Users can enter values into a cell and apply built-in formulas to perform calculations and obtain results in the target cell. When users attempt to copy and paste data into another cell, they can use the paste special option to select values, meaning that only the data is copied, excluding the formula; this is known as the absolute reference of the cell. With paste special, users can also replicate images or Unicode.

There are heightened security challenges linked with cloud computing as opposed to local data storage.

Explanation:

Cloud computing: This term refers to accessing and storing different programs and data over the internet instead of on a computer's "hard drive". The word "cloud" serves as a metaphor for the internet.

Categories:

1. Software-as-a-Service (SaaS).

2. Platform-as-a-Service (PaaS).

3. Infrastructure-as-a-Service (IaaS).

In this context, the first option is correct because the other choices do not pertain to cloud computing.

Answer:

The correct answer is option "C".

Explanation:

When a laptop or desktop computer is turned on, it typically emits a series of beeping sounds if there’s an issue with its internal components, a process known as the Power On Self Test (POST).
