How do you convert 12 grams of oxygen to moles?
Here we are given the mass of oxygen gas as 12 grams. Molar mass = 2×16 = 32 grams. We know the formula to calculate the number of moles. = 0.375 moles.
What is the formula for moles to grams?
In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.
How many moles are in 64g of O2?
molar mass of oxygen is 16 grams, it means that 1 mole oxygen weighs 16 grams. therefore 64 gram oxygen = 64/16 = 4 mole oxygen. 1 mole of any element contains 6.022 * 10^23 atoms in it. hence 4 moles of oxygen.
How many moles are in a liter of gas?
As long as the gas is ideal, 1 mole = 22.4L.
What is the mass of 4.00 moles of oxygen gas?
4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.
What is the weight of 2 moles of oxygen gas?
From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..
What is the mole of oxygen gas?
A mole of oxygen atoms 16 grams while a mole of oxygen molecules is 32 grams. A mole of nitrogen atoms is 14 grams and a mole of nitrogen molecules 28 grams, etc.
