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

PLEASE HELP!!!!!!!!!

KonstantinChe [14]

Answer:

Option "C" is the correct answer to the following question.

Explanation:

Given:

Pressure in an automobile tire (P) = 1.88 atm

Temperature (K) = 25°C = 273 + 25 = 298 Kelvin

New temperature (K1) = 37°C = 273 + 37 = 310 Kelvin

Find:

New pressure in an automobile tire (P1) = ?

Computation:

$\frac{P}{K}= \frac{P1}{K1} \\\\\frac{1.88}{298}= \frac{P1}{310}\\\\1.9557$

New pressure in an automobile tire (P1) = 1.9557

New pressure in an automobile tire (P1) = 1.96 (Approx)
