The important clue from the problem, would be (w/v). This would indicate that the percent has units of weight per volume. We calculate as follows:
Grams solute = .30 g solute / mL solution (450 mL) = 135 g of solute.
Hope this answers the question. Have a nice day.
Hello,
slope=2
y-1=2(x-4)
==>y=2x-8+1
==>y=2x-7
or 2x-y=7
For x.
All the right triangles are similar, so
.. hypotenuse/(short side) = x/6 = 6/(x -9)
Multiplying by the product of denominators gives
.. x(x -9) = 36
Two factors of 36 that differ by 9 are 12 and 3, so we have
.. x = 12
For y, we can use the Pythagorean theorem.
y^2 +6^2 = 12^2
y^2 = 144 -36 = 108
y = √108 = √(36*3)
y = 6√3
