When 7.5 moles of O2 are used up, how many grams of CO2 are formed?Mole-to-Mole Ratio:The law of definite proportions tells us that the compounds form from definite proportions and in a reaction, the reactants and products...
1. CO2 in solid form is called dry ice. You have a block of dry ice that weighs 500g. How many moles of CO2 molecules do you have? g/mole = mass of carbon atom + mass of oxygen atoms = 12.01 + 32 = 44.01g/mole amount of moles = mass of CO2 / g/mole ...
In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o

(NA=6.022×1023)atoms or molecules of a single substance. The mole is a unit widely used in chemistry as the number of moles are the ones being counted in chemical reactions, not necessarily the mass of the substances. The mole can also be related to t...
The number of moles of a substance required to react with another reactant can be calculated by using the balanced chemical reaction which provides the exact mole ratio of each reactant.Answer and Explanation: We are told to find the number of moles of oxygen required to react w...
