Question

The density of acetic acid is 1.05 g/mL. What is the volume of 327 g of acetic acid?

A
2.91 x 10-2 ml
B
3.43 x 102 mL
с
3.11 x 102 ml
D) 3.21 x 10-3 mL

Answer 1

The volume of 327 g of acetic acid with a density of 1.05 g/mL is calculated as 311.43 mL, which is 3.11 x 10^2 mL. Thus, the correct answer is option C.

Step-by-step explanation:

To find the volume of 327 g of acetic acid given that the density of acetic acid is 1.05 g/mL, you would use the following formula:

Density = Mass / Volume

By rearranging the formula to solve for volume, you get:

Volume = Mass / Density

Now, plugging the given values into the rearranged formula:

Volume = 327 g / 1.05 g/mL

Volume = 311.43 mL

Therefore, the volume of 327 g of acetic acid is 311.43 mL, which can be expressed in scientific notation as 3.11 x 102 mL, making option C the correct answer.

Answer 2

This is a chemistry problem btw. But, either way, the formula for density is mass per unit of volume. To solve for volume, bring the D over to get M/D = V
(327g)/(1.05g/ml) is the equation. Grams cancel and you’re stuck with 311.428571mL. That isn’t your answer tho, because that isn’t the right amount of sig figs. We have two figs at the least so the right answer would be 311.42 or 311.43mL. We want it in scientific notation, so move the decimal place between 3 and 1. That’s two spots to the left, so the power would be 2. C is your right answer

My chem professor told me to round to even instead of rounding up all the time. Either way, the hundreds place is always a percent error of plus or minus 0.01
