Explanation:
Because the fluid become compressible the fluid resistance increase
Empirical Formula for given compound Ba1C2N2.
<u>Explanation</u>:
<u>Step 1; </u>convert the mass of each element into their molar values by dividing available mass by molar masses.
Molar masses of required elements are as follows; Ba- 137.327, C- 12, N- 14.
<u>Step 2;</u> Divide all the values by the smallest mole value. For given compound after dividing the masses by molar masses we get 0.0690, 0.1383, 0.1378 for elements Ba, C, N respectively. Divide all three values with the least value which is 0.0690 and note these values.
<u>Step 3;</u> Convert all the numbers available into whole numbers by multiplying with suitable values. i.e. 3 if values are 0.33, 2 if values are 0.5 etc.
<u>Step 4;</u> Assign these values to corresponding elements and you will get the above empirical formula.
