Does the percentage of Oxygen drop with elevation?
No. It changes negligably from the standard ~21% regardless of elevation. (at any elevation you can survive at anyway) :p The actual amount of available oxygen does change, due to a decrease in atmospheric density as elevation increases. For example: at 17,700ft (apparently a common Mt. Everest base camp) the air density is approximately 51% of the density at sea level. So you COULD express it as 51% of ~21%, which would be about 10.71%.
How many moles of calcium ca atoms are in 98.5 g of ca?
To determine the number of moles of calcium atoms in 98.5 g of Ca, you need to first calculate the molar mass of Ca (40.08 g/mol). Then, divide the given mass by the molar mass to get the number of moles. So, 98.5 g of Ca is equal to 98.5 g / 40.08 g/mol ≈ 2.46 moles of Ca atoms.
How many moles of calcium are there in 5.00 g of Ca?
Percent CompositionFirst you have to find all the atomic masses of the elements involved in the compound. Then you have to add them up to get the total molecular mass. Take the atomic mass of Ca and divide it by the total mass. Multiply it by 100 and you will get the percent of Ca in any compound of Ca(OH)2. Once you know the percent composition, you can take Ca's percent from the whole sample. Ca: 40.1O: 16.0×2 = 32.0H2: 1.0×2 = 2.0Ca(OH)2: 74.1 grams(40.1 ÷ 74.4) × 100 = 53.9 % of Ca in Ca(OH)253.9 % of 5.00 grams = 2.67 grams of Ca in Ca(OH)2
What is the balanced equation for the neutralization of hydrogen nitrate and calcium hydroxide?
Ca(NO3)2 , Calcium nitrate Nitric acid + Calcium hydroxide ----> Calcium Nitrate + Water 2HNO3 + Ca(OH)2 ---> Ca(NO3)2 + 2H2O
What is formula of calcium chlorite?
The formula for calcium chlorite is Ca(ClO2)2.

How do you convert between the molar percentage of a compound e.g. CaO and the atomic percentage of the elements e.g. Ca and O?
To convert from the molar percentage of a compound to the atomic percentage of its elements, you can use the molar mass of each element to calculate the number of moles of each element in one mole of the compound. Then, you can use these values to determine the atomic percentage of each element. For example, in CaO, one mole of CaO contains 1 mole of Ca and 1 mole of O. So, the atomic percentage of Ca would be (molar percentage of CaO) * (molar mass of Ca) / (molar mass of CaO), and similarly for O.
