Iron has a density of 7.87 g/cm3. What is the volume in cm3 of 3.729 g of iron?

What is the molality of a solution that has 4 mol of kci in 0.800 kg of water

In which of these cases are the two wave points considered to be in phase with each other?

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
