Given the equation 2Mg + O2 --> 2MgO, how many moles of MgO are produced for every mole of O2 used up? In the acetylene torch, acetylene gas (C_2H_2) burns in oxygen to produce carbon dioxide and water. 2C_2H_2(g)+5O_2(g) \to 4CO_2(g)+2H_2O(g) How ma...
How many moles of carbon atoms do you have if you have 37.2g of carbon? How many C atoms are in 2 mol of carbon? How many moles of carbon atoms are in 1.3 moles of CH4? How many moles and atoms are in 9.00 grams of carbon?
Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles:...
(5.27 * 10^21 grams) * (1 mole / 29 grams) = 1.81 * 10^20 moles Finally, multiply by Avogadro ’s number to convert moles to molecules (1.81 * 10^20 moles) * (6.02214179*10^23 molecules/mole) = 1.09 * 10^44 molecules Written out and rounded, there are about this many molecule...
