Heptane and water do not mix, and heptane has a lower density (0.684 g/mL) than water (1.00 g/mL). A 100-mL graduated cylinder w
kicyunya [14]

Answer:

h=100.8cm

Explanation:

Hello,

In this case, considering the density and mass of both water and heptane we first compute the volume of each one:

V_{water}=\frac{m_{water}}{\rho _{water}}=\frac{34g}{1.00g/mL}=34mL\\  \\V_{heptane}=\frac{m_{heptane}}{\rho _{heptane}}=\frac{34.6g}{0.684g/mL}=50.6mL\\

Now, the total volume is:

V=50.6mL+34mL=84.6mL

Which is equal to:

V=84.6cm^3

Then, by knowing that the volume of a cylinder is πr²h or π(D/2)²h, we solve for the height as follows:

h=\frac{V}{\pi (D/2)^2} \\\\h=\frac{84.6cm^3}{\pi (3.16cm/2)^2} \\\\h=100.8cm

Best regards.
