The density of milk is about 1.07 g/ml. How many gallons weigh 5.00 kilograms, if there are 0.946 liters in a quart?

1.24 gallons

Explanation:

So first, we need to determine the volume of milk if it were 5.00 kg.

Density is calculated by the formula:

Where:

D =  Density

M = Mass

V = Volume

The density of milk is 1.07 g/ml, and the mass given to us is  kg. But as you can see, our units do not match. So what you need to do is first convert our units to match. Since we are already given the density as g/ml, then let's make kg match it by converting Kg to g.

We know that there are 1000 g in one Kg so we use that as our conversion factor.

Now let's see what our volume would be:

Now we need to convert it into gallons with what we know There are 0.946 liters in a quart, this means that there are 946 mL in a quart.

So there we convert quarts to gallon. There are 4 quarts in a gallon.

We then use that as for as a conversion factor:

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
