The formula of aluminium oxide is Al2O3. So the molecular weight will be 27*2 plus 16*3. That is 102. The molecular weight of aluminum is 27. So the ratio aluminium oxide to aluminium will be 102 to 27. That is 3.38 to 1.

∙ 15y agoYou would use the atomic masses of Cu and O so that would be 63.55+16.00 that equals 79.55

∙ 15y agoIt depends on what type of Copper you have.
Copper (I) Oxide is 2:1
Copper (II) Oxide is 1:1
Copper (III) Oxide is 2:3

What is the mole ratio between the iodate and thiosulphate ions?
1:6
When 2.50 g of copper reacts with oxygen the copper oxide product has a mass of 2.81 What is the simplest formula of the copper oxide?
(2.5 grams =) 0.0393 moles of copper reacts with (0.31* grams =) 0.0194 moles of oxygen to produce something that has a ratio of 2.0 moles copper to 1 mole oxygen. Copper has a +1 and a +2 oxidation state and Oxygen has (usually) a -2 oxidation state so we know it isn't CuO because that's a 1:1 ratio. Cu2O has a 2:1 ratio...what could it be? *notice that the subtraction: 2.81g - 2.50 g = 0.31 g, reduced my significant digits to two.
What is the mole to mole ratio for sodium chloride?
The formula is: NaOH(aq) + HCl(aq) --> NaCl + H2O(l) So the ratio is: 1 : 1 : 1 : 1
What is the mass in grams of one atom of copper?
The periodic table states that the molar mass of copper is 63.546 grams per mole. That means that if you have one mole of copper, it will weigh 63.546 grams. One mole is 6.022x1023 (Avogadro's number) atoms. To find the mass of one copper atom in grams, you simply divide copper's molar mass by the number of atoms in one mole. 63.546 / 6.022x1023 = 1.055x10-22 One atom of copper weighs 1.055x10-22 grams.
What is the mole ratio of nitrogen to ammonia in the equation 1N2 3H2 equals NH3?
The balanced equation for the reaction is N2 + 3H2 --> 2NH3 Thus, the mole ratio of nitrogen to ammonia in the balanced equation is 1:2.
How does the experimental mole ratio compare with the theoretical mole ratio?
the experimental mole ratio has a bigger penis
What is the mole ratio between the iodate and thiosulphate ions?
1:6

What is molecular density?
the ratio between the mass of one mole of a substance and its volume is the molecular density....
How is mole ratio used in stoichiometry?
to find how much moles are obtained between two compounds
What can be said about 1 mole silver and 1 mole gold?
1 mole of silver would be 108g and 1 mole of gold 197g.
Why is one mole of aluminum larger than one mole of copper?
It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.
What is the mole ratio of salt to water in NA2SO4.10H2O?
An anhydrous sals hasn't water.
What is the mole ratio for KCl?
KCl
What is the mole ratio of potassium chloride?
1:1, one mole potassium to one mole chlorine
What is the mole fraction of solute in a 3.30 m aqueous solution?
This is the ratio between the molar concentration of this solute and 3,3.
Why does a mole of copper atoms weigh less than a mole of lead atoms?
Because copper has a smaller molar mass, hence it will have less mass per mole than lead.
