Explanation:

<em>Hi</em><em> </em><em>there</em><em>!</em><em>!</em>

<em>you</em><em> </em><em>asked</em><em> </em><em>to</em><em> </em><em>multiply</em><em> </em><em>these</em><em> </em><em>all</em><em> </em><em>right</em><em>,</em>

<em>you</em><em> </em><em>can</em><em> </em><em>simply</em><em> </em><em>multiply</em><em> </em><em>it</em><em> </em><em>,</em>

<em>=</em><em>3</em><em>cm</em><em> </em><em>×</em><em> </em><em>4</em><em> </em><em>cm</em><em> </em><em>×</em><em> </em><em>1</em><em>cm</em>

<em>=</em><em> </em><em>1</em><em>2</em><em>cm</em><em>^</em><em>2</em><em>×</em><em>1</em><em>cm</em><em> </em><em> </em><em> </em><em> </em><em>(</em><em>4</em><em>×</em><em>3</em><em>=</em><em>1</em><em>2</em><em>)</em>

What is the ph of a solution that has a poh of 11.24
galina1969 [7]
Always remember that pH + pOH = 14 
Here, you have a pOH of 11.24, so  you replace it in the equation, and u get:
pH + 11.24 = 14

Then, You move 11.24 to the other part. and moving from a part to another change the sign of the equation. And you get:
pH = 14 - 11.24 = 2.76

So, the pH of a solution that has a pOH of 11.24 is pH = 2.76

Hope this Helps :)

When solving a problem it is important to identify your given and needed units, but it is also important to understand the relat
UNO [17]

Answer:

See Explanation

Explanation:

Given

(a) to (d)

Required

Determine whether the given parameters can calculate the required parameter

To calculate either Density, Mass or Volume, we have

Density = \frac{Mass}{Volume}

Mass = Density * Volume

Volume = \frac{Mass}{Density}

(a) 432 g of table salt occupies 20.0 cm^3 of space

Here, we have:

Mass = 432g

Volume = 20.0cm^3

The above can be used to calculate Density as follows;

Density = \frac{Mass}{Volume}

Density = \frac{432g}{20.0cm^3}

Density = 21.6g/cm^3

(b) 5.00 g of balsa wood, density of balsa wood : 0.16 g/cm^3

Here, we have:

Mass = 5.00g

Density = 0.16g/cm^3

This can be used to solve for Volume as follows:

Volume = \frac{Mass}{Density}

Volume = \frac{5.00g}{0.16g/cm^3}

Volume = 31.25cm^3

(c) 32 cm^3 sample of gold density of 19.3 g/cm^3

Here, we have:

Volume = 32cm^3

Density = 19.3g/cm^3

This can be used to calculate Mass as follows:

Mass = Density * Volume

Mass = 32cm^3 * 19.3g/cm^3

Mass = 617.6g

(d) 150 g of iron, density of Iron = 79.0 g/cm^3

Here, we have

Mass = 150g

Density = 79.0g/cm^3

This can be used to calculate volume as follows:

Volume = \frac{Mass}{Density}

Volume = \frac{150g}{79.0g/cm^3}

Volume = 1.90 cm^3 <em>Approximated</em>
