We're told oxygen is the most common element in the Earth's solid crust. But how much oxygen is there? Let's compare to the amount of oxygen in the Earth's atmosphere, like this: The most common minerals in the Earth's crust are feldspars, and anorthite (CaAl, Si,O,) is a typical feldspar. Let's assume the entire crust is made of anorthite, with a density of 2.8 g/cm. • The radius of the Earth is 6371. km and let's say the crust is the upper 50.0 km of it. • Let's model the Earth's atmosphere as a layer on top of the Earth about 100. km thick with an average density of 0.99 g/m, and which is 23.1% oxygen by mass. Jse this information to calculate the ratio of the mass of oxygen in the Earth's atmosphere to the mass of oxygen in the Earth's crust. Round your answer to 2 significant digits.

We're told oxygen is the most common element in the Earth's solid crust. But how much oxygen is there? Let's compare to the amount of oxygen in the Earth's
atmosphere, like this:
• The most common minerals in the Earth's crust are feldspars, and anorthite (CaAl, Si,O,) is a typical feldspar. Let's assume the entire crust is made of
anorthite, with a density of 2.8 g/cm.
• The radius of the Earth is 6371. km and let's say the crust is the upper 50.0 km of it.
• Let's model the Earth's atmosphere as a layer on top of the Earth about 100. km thick with an average density of 0.99 g/m°, and which is 23.1% oxygen
by mass.
Use this information to calculate the ratio of the mass of oxygen in the Earth's atmosphere to the mass of oxygen in the Earth's crust. Round your answer to 2
significant digits.

3. Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solution is water. In a hardware store, you can buy industria strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume o vinegar. But one volcano uses 5% vinegar and the other volcano uses 30% vinegar. He measures the volume of gas production for the'first minute of each reaction, and he records the data below.
