Fish in a frozen lake can survive throughout the winter months due partially to the fact that lakes don't freeze solid. Fresh water has a density
of 1.00 g/cm3. A piece of ice has a mass of 57g and a volume of 62 cm3.
Give the density of the piece of ice (use the density formula d = m/V) and
explain what will happen to it in the lake.

Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
