How would you make 300ml of a mixture of toluene and hexane in a ratio of 70:30 respectively?

~I really don't know how I would do this...would I do this?:

xT + yH= 300ml

xT= 300ml- yH

then plug that in? That came out funny though since I get 0 in the end...

~Help Please~

Thanks

I assume this is a volume ratio.

70 + 30 per 100 mL.
270 + 90 per 300 mL.

Oh..so that's how that works..

Thank you Dr.Bob =)

i don't understand please help.

To make a 300ml mixture of toluene and hexane in a ratio of 70:30 respectively, you can follow these steps:

1. Determine the total volume of each component by multiplying the desired ratio to the total volume of the mixture.

Total volume of toluene = (70/100) * 300ml = 210ml
Total volume of hexane = (30/100) * 300ml = 90ml

2. Start with the first component, toluene. Measure out 210ml of toluene using a graduated cylinder or measuring container.

3. Next, measure out 90ml of hexane using a separate graduated cylinder or measuring container.

4. Combine the measured volumes of toluene and hexane in a container or flask to create the desired mixture. Make sure to mix them thoroughly to ensure they are evenly distributed.

By following these steps, you can create a 300ml mixture of toluene and hexane in a 70:30 ratio respectively as desired.
