1 Empirical formula is a comparison of the number of moles of a compound so you need your values in moles. 2  Using the oxygen example again, there are 16.0 grams per mole of oxygen so 40 grams of oxygen would be 40/16 = 2.5 moles of oxygen.hen you have the molar mass you can find the ratio of the actual mass of the compound to the empirical mass. If the ratio is one (as with water, H 2 O), then the empirical formula and molecular formula are the same.
Weather in Yosemite in July. The average maximum daytime temperature in Yosemite in July is a warm 23Â°C (73Â°F). There are usually 12 hours of bright sunshine each day, which represents 81% of the 14 hours of daylight. Expect 19mm (0.7 inches) of rainfall across the whole of July with 5 days with some rain falling.
Yosemite Valley, along with Wawona Meadow, lies at an elevation of 4,000 feet (1,200 meters). Only the Hetch Hetchy area is lower. The Glacier Point Road starts at an elevation of 6,000 feet (1,800 meters) and climbs from there, and the Tioga Road ranges from 6,000 to 10,000 feet (1,800 to 3,000 meters).So expect temperatures in most other areas of the park to be lower than they are in Yosemite Valley.eather Underground broadcasts a 5-day forecast and local radar map, with current temperature data from a location near Groveland, 25 miles northwest of Yosemite's Big Oak Flat entrance.
