1 mole of oxygen = 16 grams8/16 = 0.5 moles
If your question is " how many moles of oxygen are in 65.06 grams?" we should consider the gas O2 which has an atom/mol weight of 16 grams: 65.06/16= 4.06625 moles
The amount of grams in two moles depends on the element or compound that you have two moles of. For example, the molar mass of oxygen is about 16 grams. So two moles of oxygen would be about 32 grams.
1 mole of oxygen weighs 16 grams. So, 1.8 moles would weigh 1.8 x 16 = 28.8g
The Atomic Mass of Oxygen is 16 (15.9998) 16 * 0.05 = 0.8 grams
C8H18. I assume you mean how many moles octane in 16 grams. 16 grams C8H18 (1 mole C8H18/114.224 grams) = 0.140 moles octane
16 g helium is equivalent to 4 moles.
There are approximately 4.0 moles of Helium in 16 grams of the element.
He = helium 16 grams He (1 mole He/4.003 grams) = 3.99 moles He You can call it 4.0 moles He
22 grams carbon dioxide (0.5 moles)
How many moles of magnesium are needed to react with 16 g of molecular oxygen?
100 grams oxygen (1 mole O/16 grams)(2 mole Fe/3 mole O) = 4.17 moles iron --------------------------
moles = mass/molar mass The molar mass of an oxygen atom = 16 g mol-1, as there are two oxygen atoms in diatomic oxygen this has to be doubled. 42g / 32g mol-1 = 1.3125 moles
CH4 + 2O2 -> CO2 + 2H2Omoles of H2O produced = 36/18 = 2moles of CO2 produced = 44/44 = 1moles of CH4 reacted = 16/16 = 1so moles of O2 consumed = 2 i.e 2 X 32 g = 64 g of O2
A mole is the measument of a single, in this case oxygen molecule. Oxygen on the periodic table is shown like this 8 O 16.00 The 16 is showing the atomic mass. So to answer the question above the answer is ... There are 1,600 moles in 100 grams of oxygen
the equation of this reaction is C + O2 = CO2 (s) (g) (g) according to this reaction 1mol of Carbon react with same number of moles of Oxygen. and this combination gives 1mol of CO2 as result. so first we have to find the number of moles in the weight we are going to use. 12 grams of carbon contains 1mol so 6 grams of carbon contains ( 1/12 )*6 = 0.5mol 32 grams of Oxygen contains 1mol 16 grams of Oxygen contains ( 1/36 )*16 = 0.5mol as 1mol of C react with 1mol of O2,0.5mol of C react with 0.5mol of O2. this produces equal number of moles (0.5mol) of CO2.
Density of lquid oxygen: 1,141 kg/L Atomic weight of oxygen: approx. 16 Moles: 71,31
16 g oxygen is equal to 0,5 mole
There is 1 mole of water for every 18 grams of water (the atomic mass of oxygen is 16 and the atomic mass of hydrogen is 1 gram, so 16 + 1 + 1 = 18).
Answer: 16 g of oxygen and 2 g of hydrogen.
4.8/16 moles of oxygen atoms converts to 1.6/16 moles of ozone molecules.
Moles = mass / relative molecular mass. 360 / 1 + 1 + 16 = 20 moles
Look up the molecular weight of carbon dioxide in the periodic table. The formula for carbon dioxide is CO2, which means one atom of carbon and two atoms or oxygen per molecule of carbon dioxide. Carbon has molecular weight of 12. Oxygen molecular weight is 16. Total 12+16+16= 44 11 grams/44 grams/mole=0.25 moles of carbon The grams of water and combustion of 7.5 grams are totally irrelevant. They are only given to possibly confuse you.
There are many different ways to calculate the moles and grams of oxygen. but one mole of oxygen is always gonna equal 32 grams because its diatomic, meaning it only comes in nature as O2. so it would be the atomic mass of oxygentimes 2. 16*2= 32
