The volume of the object=6.71ml

Given:

Mass of the object=36.240g

Density of the object=5.40\frac{g}{m l}

To find:

Volume of the object

<u>Step by Step Explanation:</u>

Solution:

According to the formula, Density of the object is given as

\rho=\frac{m}{v} and from this volume can be derived as

v=\frac{m}{\rho}

Where, m=mass of the cylinder

\rho=density of the cylinder

v=volume of the cylinder

We know the values of m=36.240g and \rho=5.40\frac{g}{m l}

Substitute these values in the above equation we get

v=\frac{m}{\rho}

v=36.240/5.40

=6.71ml

Result:

Thus the volume of the object is 6.71ml

A gas at 1.2 atm has a
Papessa [141]

Answer:

1.26 mole

Explanation:

Using ideal gas law

PV=nRT

R= 0.08206

T=273+87=360

1.2×31=n×0.08206×360

37.2 =n × 29.54

n= 1.26 mole

a book with a mass of 1 kg is dropped from a height of 3 m. what is the potential energy of the book when it reaches the floor?
mafiozo [28]
Well, first of all, the formula for finding potential energy is;
PE=mgh
  Where; m is the mass
               g is the gravitational force or acceleration due to gravity
                h is the height. 
   Anyway, according to the question, the mass is 1kg, the acceleration due to gravity has a constant value of 10ms² . And the height is 3m. Now you just have to use all these in the formula. So;
mgh= 1 x 10 x 3. That will be 30. And the unit of potential energy is Joule. So the answer is 30 joules. Hope i helped. Have a nice day.

Find the mass of one atom of uranium-235. Recall that the mass in atomic mass units is equal to the mass in grams of one mole of
stiv31 [10]

Answer:

3.90*10^{-25}kg/atom

Explanation:

The molar mass of uranium-235 is 235 g/mol. So one mole of uranium-235 has a mass of 235 g. Put differently 6.022×10^23 atoms of uranium-235 have a mass of 235 g. Knowing that, how can we use that to find the mass of one atom?

mass of one atom = \frac{235 g}{1mol} *\frac{1 mol}{6.022*10^{23}atoms } *\frac{1kg}{1000g}= 3.90*10^{-25}kg/atom
