What is the specific gravity of a substance with density 100 kg/m3with...
Calculation of Specific Gravity
To calculate the specific gravity of a substance with a density of 100 kg/m3 with respect to a reference substance of density 100 lb/m3, we need to use the formula for specific gravity:
Specific Gravity = Density of Substance / Density of Reference Substance
Conversion of Density Units
First, we need to convert the density of the substance from kg/m3 to lb/m3. Since 1 kg/m3 is approximately equal to 0.06243 lb/ft3, we can multiply the density of the substance (100 kg/m3) by 0.06243 to get the density in lb/m3.
100 kg/m3 * 0.06243 lb/ft3 = 6.243 lb/ft3
Calculation of Specific Gravity
Now, we can calculate the specific gravity using the converted density of the substance (6.243 lb/ft3) and the density of the reference substance (100 lb/m3):
Specific Gravity = 6.243 lb/ft3 / 100 lb/m3
Specific Gravity = 0.06243
Therefore, the specific gravity of the substance with a density of 100 kg/m3 with respect to a reference substance of density 100 lb/m3 is approximately 0.06243, which is equivalent to 2.2 when rounded to one decimal place.
Therefore, the correct answer is option B) 2.2.

100 kg/m3 * 0.06243 lb/ft3 = 6.243 lb/ft3
Calculation of Specific Gravity
Now, we can calculate the specific gravity using the converted density of the substance (6.243 lb/ft3) and the density of the reference substance (100 lb/m3):
Specific Gravity = 6.243 lb/ft3 / 100 lb/m3
Specific Gravity = 0.06243
Therefore, the specific gravity of the substance with a density of 100 kg/m3 with respect to a reference substance of density 100 lb/m3 is approximately 0.06243, which is equivalent to 2.2 when rounded to one decimal place.
Therefore, the correct answer is option B) 2.2.
