Calculate the density of a cube of iron that measures 3.50cm, 0.755 cm, 2.25cm on each side and weighs 47.0g?

laila [671]

Answer: 7.90 g/cm^3

Explanation:

Density = Mass / Volume

The first step is to find the volume by multiplying the three measures of the cube that have been provided.

3.50 x 0.755 x 2.25 = 5.95 cm^3

Now we can plug the numbers into our equation.

Density = 47.0g / 5.95 cm^3

Density = 7.90 g/cm^3

4. Calculate the concentration of NaCl in a solution prepared by diluting 2 mL of 0.05 M NaCl to a total volume of 10 mL with de

Shalnov [3]

Answer:

Molarity of NaCl = Molarity of sodium ions = Molarity of chloride ions = 0.01 M

Explanation:

Considering

$Molarity_{diluted\ solution}\times Volume_{diluted\ solution}=Molarity_{stock\ solution}\times Volume_{stock\ solution}$

Given that:

$Molarity_{diluted\ solution}=?$

$Volume_{diluted\ solution}=10\ mL$

$Volume_{stock\ solution}=2\ mL$

$Molarity_{stock\ solution}=0.05\ M$

So,

$Molarity_{diluted\ solution}\times 10\ mL=0.05\ M\times 2\ mL$

$Molarity_{diluted\ solution}=0.01\ M$

<u>Molarity of NaCl = Molarity of sodium ions = Molarity of chloride ions = 0.01 M</u>

Rina8888 [55]

Explanation:

Given that,

Volume of a hallow glass sphere is 350 mL

Specific gravity is 1.252

We need to find the weight of the sphere. The ratio of density of substance to the density of water is called specific gravity.

The density of water is 1 g/mL

$\text{specific gravity}=\dfrac{\text{density of substance}}{\text{density of water}}\\\\SG=\dfrac{m}{V\times \rho_w}\\\\m=SG\times V\times \rho_w\\\\m=1.252\times 350\ mL\times 1\ g/mL\\\\m=438.2\ \text{grams}$

We know that,

1 pound = 453.592 grams

So,

m = 0.97 lbs

So, the weight of the sphere is 0.97 lbs or 0.97 pounds.
