Question

What is the cost of 1000 ml of glycerin, specific gravity 1.25, bought at $54.25 per pound?

a) $12.38
b) $54.25
c) $68.75
d) $270.62

Answer 1

The cost of 1000 ml of glycerin, with a specific gravity of 1.25, is $149.50 when bought at $54.25 per pound. None of the provided options in the question match this calculated amount, suggesting an error in the available choices.

Step-by-step explanation:

The cost of 1000 ml (which is 1 liter) of glycerin with a specific gravity of 1.25 can be determined by first calculating the weight of glycerin in pounds and then finding out the cost by multiplying it by the given price per pound.

• 1 liter of water has a mass of 1 kilogram.
• Glycerin specific gravity is 1.25, so 1 liter of glycerin weighs 1.25 kilograms.
• There are 2.20462 pounds in a kilogram, so 1.25 kilograms of glycerin equals 2.755775 pounds.
• The cost of glycerin per pound is $54.25.

Now, we multiply the weight in pounds by the cost per pound to get the total cost of glycerin:
2.755775 pounds × $54.25 per pound = $149.49501375.

Therefore, the closest answer choice to the calculated cost is $149.50, none of the provided options (a) $12.38, (b) $54.25, (c) $68.75, (d) $270.62, match the correct calculation, indicating a possible error in the question or the provided selections.
