The molar mass of carbon tetrachloride (ccl4) is 153.81 g/mol. select the best answer from the choices provided true or false

Hi!

To find molar mass of a compound, we need to use the periodic table and add up each individual masses.

In this case if we look at the periodic table, C or Carbon has a molar mass of 12.01.grams and tetrachloride or 4 chlorine 35.45grams

You need to remember to times 35.45 by 4 to count for all the chlorine.

If you add 12.01 g + 141.8 = 153.81 g/mol

Therefore your answer is true!

Hope this helps!

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.
