One method of estimating the temperature of the center of the sun is based on the assumption that the center consists of gases that have an average molar mass of 2.00 g/mol. If the density of the center of the sun is 1.40 g/cm3 at a pressure of 1.30 × 109 atm, calculate the temperature?

Determine the range of fat you might expect to obtain if you extracted fat from ten grams of nutmeg (Dried, ground nutmeg typically contains between 20-25% fat by weight.) Assume that your extraction is 95% effective.
Discuss how to find the molar mass of a compound, percent composition of the elements of a compound and how to determine the empirical and molecular formulas from percent composition.
calculate that how many liters of carbon monoxide gas, measured under the same conditions, is essential?
Hydrogen gas is contained in a one-liter vessel at "STP"(0 degrees Celsius and 1 Std. Atm.). Flourine gas is contained in a second one-liter vessel at the same conditions of temperature and pressure.
