How many moles of nh3 are produced from 1.5 moles h2?
1 mole
How many moles are in 68 grams of copper (2) hydroxide?
I mole of copper hydroxide is 98g (64 + 16 + 1 + 16 + 1) So 68g is 68/98 moles = 0.694g I have used 64 for the ram of copper. Your list might use a slightly different value, so substitute that.
How many moles of hydrated copper sulphate are contained in 5.00g of the substance?
5 mole copper (6.022 X 1023/1 mole Cu) = 3 X 1024 atoms of copper -----------------------------------
How many moles of sodium in 5.25 mole of Na2SO4?
5,25 moles (in anhydrous sodium sulphate)
If you have 1.20 and times 1024 atoms of copper how many moles of copper do you have?
1.20x10^24 atoms x 1 mole/6.02x10^23 atoms = 1.99 moles
How many moles are present in 6.022 x 1023 atoms of Cr?
Only one mole of copper.
How many atoms are in 0.75 moles of neptunium?
6.02 X 1023 particles per mole X .75 moles = 4.52 X 1023 molecules.
How many moles of oxygen atoms combine with 127 g of copper?
One mole of oxigen (O2-the diatomic molecule) is needed for 127,092 g copper to form CuO.
How many atoms present in 1 cubic centimeter of copper with a density of 8.96g cm3?
From the density and volume, the mass of this amount of copper is 8.96 grams. There are 63.546 grams in 1 mole of copper, so this is 0.141 moles. There are 6.023 x 10²³ atoms in 1 mole. Multiply this by 0.141 moles = 8.492 x 10²² atoms.
How many moles of carbon are in 3.5 moles of calcium carbonate?
3.5 moles CaCO3 (1 mole carbon/1 mole CaCO3) = 3.5 moles
How many moles of H are in 2.95 moles of water?
2.95 mole H2O (2 moles H/1 mole H2O) = 5.90 moles hydrogen ------------------------------
How many electrons in 2.9 grams of copper?
i havent got an elements table in front of me but here is how you do it: figure out how many moles is 2.9 grams of copper by using molecular wieght, then simply multiply so: No of moles* No of atoms in one mole* number of electrons in one atom of copper (which is the same as the No of protons...)
How do you calculate the mass of 14.5 moles of copper?
1 mole of Copper has a mass of 63.546 g. So, 14.5 moles will be 14.5 times that amount. Do the math.
How many moles of oxygen are in one mole of calcium carbonate?
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
