I am having a really hard time setting this problem up to solve can anyone help?
Hexane has a density of 0.659 g/mL. How many (mL) would a student need to pour in order to get 49.5g of hexane?
Sure, I can help you with that. To solve this problem, we can use the formula:
Mass = Density x Volume
We are given the mass of hexane (49.5g) and the density of hexane (0.659 g/mL), and we need to find the volume (in mL) that corresponds to this mass.
To use the formula, we rearrange it to solve for volume:
Volume = Mass / Density
Now we can substitute the given values into the formula:
Volume = 49.5g / 0.659 g/mL
To find the volume, we divide the mass by the density.
Using a calculator, the calculation would be:
Volume = 75.11 mL
Therefore, a student would need to pour 75.11 mL of hexane in order to obtain 49.5g of hexane.
