Question

A water sample shows 0. 091 grams of some trace element for every cubic centimeter of water. Valeria uses a container in the shape of a right cylinder with a diameter of 15. 2 cm and a height of 16. 2 cm to collect a second sample, filling the container all the way. Assuming the sample contains the same proportion of the trace element, approximately how much trace element has Valeria collected? Round your answer to the nearest tenth

Answer 1

First, we need to find the volume of the cylinder:

V = πr^2h = π(7.6 cm)^2(16.2 cm) = 2,945.27 cm^3

Next, we can find the amount of trace elements collected:

0.091 g/cm^3 x 2,945.27 cm^3 = 267.68 g

Rounded to the nearest tenth, Valeria collected approximately 267.7 grams of the trace element.
