Hydrogen gas has a density of 0.090 g/L, and at normal pressure and 3.28 C one mole of it takes up 22.4 L. How would you calculate the moles in 330. g of hydrogen gas? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols.

You have two distinct gaseous compounds made from element X and element Y. The mass percents are as follows: Compound I: 30.43% X, 69.57% Y Compound II: 63.64% X, 36.36% Y In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react gas X with gas Y to make the products, you get the following data (all at the same pressure and temperature): 1. volume gas X + 2 volumes gas Y2 volumes compound I 2. volumes gas X + 1 volume gas Y2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element X and element Y.
Suppose that you are closing a cabin in the north woods for the winter and you do not want the water in the toilet tank to freeze. You know that the temperature might get as low as 30. C, and you want to protect about 4.0 L water in the toilet tank from freezing. Calculate the volume of ethylene glycol (density = 1.113 g/mL; molar mass = 62.1 g/mol) you should add to the 4.0 L water.
Hydrogen gas has a density of 0.090 g/L, and at normal pressure and - 2.78 °C one mole of it takes up 22.4 L. How would you calculate the moles in 990. g of hydrogen gas? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols. moles = x10 degreenobox
Part A: For calculations involving gaseous systems, it is important to use the kelvin temperature scale. What is the temperature in kelvin if a thermometer reads 221 °C? Part B: If we are given the temperature in Kelvin, we may need to turn this back into Celsius (most thermometers use the Celsius scale). A gas has a temperature of 286 K. What is this temperature in Celsius?
