How do you convert mass to volume without density?

 How do we find the volume of an object without knowing neither the density nor the mass? The formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The formula can use any two of the values to calculate the third.

The formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The formula can use any two of the values to calculate the third. Density is defined as mass per unit volume. In this scenario you would need to know at least 2 variables. However if you ignore the formula, you can figure this using displacement.

1. Add water to a graduated cylinder. Choose a graduated cylinder that the object will easily fit inside. Tilt the cylinder while pouring the water to reduce bubbles. Pour enough water in to fill the cylinder to the halfway mark.

2. Read the meniscus. You will notice that the water is higher on the sides of the cylinder and droops slightly in the middle. This droop is known as the meniscus and is the standard point at which the water level is measured. Make sure that the cylinder is on a flat, level surface and that there are no bubbles. Look closely where the meniscus rests

3. Record your measurement. It will be important to know the initial water level exactly. Write down the measurement that you took in a table or lab notebook. Your measurement will be mL.

4. Submerge your object. Tilt the cylinder. Slide the object into the water slightly. Be sure that your object is completely submerged in the water. If there is not enough water to submerge the object, you will have to start over with more water in the cylinder.

5. Take a new measurement. Let the object and the water settle. Make sure that the cylinder is on a flat level surface. Now look at the water level (again read the meniscus). The water level should have increased with the object being added to the cylinder.

6. Record your final measurement. The final measurement will be just as important as the initial measurement in your calculations. It too must be precise. Write down the final water level in mL in your table or lab notebook.

7. Last, solve for the difference between water levels. You will set up the equation Vtotal - Vwater = Vobject.

Vtotal is your final measurement, Vwater is your initial measurement, and Vobject is the volume of your object. In other words, subtract the first measurement from the second to find the volume of your object.

Well, you could always just put it onto a scale to find the mass. But assuming you aren't talking about a laboratory setting. sorry if its all werid i cant really put it into how it supposed to be

The general formula is:

ρ

=

m

V

where

ρ

is density in

g/mL

if mass

m

is in

g

and volume

V

is in

mL

.

So to get the mass...

m

=

ρ

V

Or to get the volume...

V

=

m

ρ

When you have the volume and not the density, and you want to find mass, you will need to find the density yourself. It's often readily available on the internet.

Just replace "[...]" with the object you want, and if it's not exactly what you need, consider it an estimate.

These days, you should be able to search for the density of any common object.

When you have the density and volume but not the mass, then just make up a mass.

You shouldn't need specific numbers to do a problem. You can always solve a problem in general and get a solution formula. If you need to, just make up some numbers that you know how to use.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
