What volume of 1.25 M sodium hydroxide (NaOH) solution can be prepared using 60.0 g of sodium hydroxide? (The mass of one mole o
nataly862011 [7]

Answer:

The answer is

<h2>1.20 L</h2>

Explanation:

Since the concentration , mass and molar mass of NaOH has been given we use the formula

<h3>C =  \frac{m}{M \times v}</h3>

To find the volume

where

C is the concentration

m is the mass

M is the molar mass

v is the volume

Making volume the subject we have

<h3>v =  \frac{m}{C \times M}</h3>

From the question

C = 1.25 M

m = 60 g

M = 40.0 g/mol

Substitute the values into the above formula and solve for the volume

We have

<h3>v =  \frac{60}{1.25 \times 40}  \\ v =  \frac{60}{50}  \\ v =  \frac{6}{5}</h3>

We have the final answer as

<h3>Volume = 1.20 L</h3>

Hope this helps you

Alkanes are hydrocarbons containing only single bonds. Acyclic alkanes have carbon atoms arranged in chains, whereas cycloalkane
sashaice [31]

Answer:

156 Hydrogen atoms

Explanation:

<u>Any acyclic alkane has a molecular formula that can be expressed as</u>:

CₙH₂ₙ₊₂

Where <em>n</em> is any integer and the number of carbon atoms. For example, Propane has 3 carbon atoms, this means it would have [2*3+2] 8 hydrogen atoms, resulting with a formula of C₃H₈.

An acyclic alkane with 77 carbon atoms would thus have:

2*77 + 2 = 156 hydrogen atoms
