<h3><u>Answer;</u></h3>

Find the number of 1-foot cubes that fill the fish tank

<h3><u>Explanation;</u></h3>

Volume of a cuboid such as the fish tank is given by the product of length width and height;

Such that; Volume = length × width × height

Similarly, we can count the number of 1 foot cube that can fill the fish tank.

And since each cube has a volume of 1 cubic ft, then the number of cubes will be equivalent to the volume of the fish tank in cubic ft.

In an investigation with density, Marcia’s teacher measures the mass and volume of 10 different samples of a substance. The samp
valina [46]

Answer:

Mass  

Step-by-step explanation:

Usually, you plot the independent variable along the horizontal (x) axis and the dependent variable along the vertical (y) axis.

Marcia's teacher plotted the mass of the sample along the x-axis and volume along the y-axis.

The mass is the independent variable, because that is <em>what the teacher varied</em>.

The volume is the <em>dependent variable</em>, because it <em>depends</em> on the mass.

Sample number is <em>wrong</em>, because it is not a variable.

Substance is <em>wrong</em>, because all samples consist of the same substance.

Density is <em>wrong</em>, because it is constant. It is the slope of the graph.

Answer:

1249.88 mol.

Explanation:

∵ no. of moles of Fe = mass of Fe/atomic weight of Fe.

<em>∴ no. of moles of Fe </em>= (6.98 x 10⁴ g)/(55.845 g/mol) = <em>1249.88 mol.</em>

Argon has a pressure of 34.6 atm. It is transferred to a new tank with a volume of 456 L and pressure of 2.94 atm. What was the
NemiM [27]

Answer:

38.75 L

Explanation:

From the question,

Applying Boyles Law,

PV = P'V'....................... Equation 1

Where P = Original pressure of the Argon gas, V = Original Volume of Argon gas, P' = Final pressure of Argon gas, V' =  Final Volume of Argon gas.

make V the subject of the equation

V = P'V'/P.................... Equation 2

Given: P = 34.6 atm, V' = 456 L, P' = 2.94 atm.

Substitute these values into equation 2

V = (456×2.94)/34.6

V = 38.75 L
