How many grams of oxygen wil be in two moles of potassium dichromate?
224 g are in two moles of potassium dichromate.
How many moles of sulfur trioxide will be produced when two moles of sulfur combine with three moles of oxygen?
2s + 3o2 --> 2so3
How mony moles of oxygen atoms do 1.5 moles of Co2 contain?
0.75 moles of any substance is 0.75(6.02x1023) = 4.52x1023 particles. If those particles are CO2 molecules, and each molecule has 2 oxygen atoms, then it's 2(4.52x1023) = 9.04x1023 oxygen atoms.
How many moles of oxygen gas are needed to make 4 moles of water?
4 moles of oxygen atoms are present in 4 moles of H2O
In the reaction 2CO plus O2 equals 2CO2 what is the ratio of moles of oxygen used to moles of CO2 produced?
If you mean atoms then two, if molecules one.

Which best represents the number of moles in exactly 64 grams of oxygen (O2)?
The number of moles in exactly 64 grams of oxygen (O2) is two.
What is 42 grams of diatomic oxygen in moles?
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
How many moles are in 64 g of oxygen?
4.80 grams O2 (1 mole O2/32 grams ) = 0.150 moles of O2
How mony moles of oxygen atoms do 1.5 moles of Co2 contain?
0.75 moles of any substance is 0.75(6.02x1023) = 4.52x1023 particles. If those particles are CO2 molecules, and each molecule has 2 oxygen atoms, then it's 2(4.52x1023) = 9.04x1023 oxygen atoms.

How many moles of oxygen are there in one mole of hydrogen peroxide?
two
The formula potassium dichromate is K2Cr2O7. How many grams of oxygen will be in 2 moles of potassium dichromate?
In one mole of potassium dichromate, there seven moles of oxygen. This means in two moles of K2Cr2O7, there are 14 moles of O, or 7 Moles of O2, which equals 224 grams.
How much oxygen is needed to ignite gasoline?
The combustion reaction of petrol is commonly 2 C8H18 + 25 O2 -> 16 CO2 + 18 H2O. So for every two moles of petrol, 25 moles of oxygen are required. Thus for the 6.15 moles of gas, 153.75 moles of O2 are needed or 3440 liters.
How many mol of oxygen in 3.5 mol of caffeine.?
The molecular formula for caffeine is C8H10N4O2. As can be seen each mole of caffeine contains TWO moles of O. Thus 3.5 moles caffeine x 2 moles O/mole caffeine = 7.0 moles oxygen
