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.
You would use the atomic masses of Cu and O so that would be 63.55+16.00 that equals 79.55
It 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
This depends on the mass of copper oxide.
Cu : O = 63.55 : 16.00
2:1
1:6
(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.
The formula is: NaOH(aq) + HCl(aq) --> NaCl + H2O(l) So the ratio is: 1 : 1 : 1 : 1
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.
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.
the experimental mole ratio has a bigger penis
1:6
The number is 6,022140857.10e23.
the ratio between the mass of one mole of a substance and its volume is the molecular density....
to find how much moles are obtained between two compounds
1 mole of silver would be 108g and 1 mole of gold 197g.
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.
An anhydrous sals hasn't water.
KCl
1:1, one mole potassium to one mole chlorine
This is the ratio between the molar concentration of this solute and 3,3.
Because copper has a smaller molar mass, hence it will have less mass per mole than lead.
