Calculate the molar mass of sodium chloride. Calculate the number of moles in 25.0 grams of KNO3. Calculate the amount in moles for NaCl in 5.85 g of salt. Calculate the mass, in grams, of 0.52 moles of potassium. Calculate the mass in grams of 5.0 moles of potassium....
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
Determine the mass, in grams, of 0.04760 moles of (NH4)3PO3. How do you find the total mass of a compound when you are only given that it has 1.04 g K, 0.70 g Cr, and 0.86 g O? Calculate the molecular mass (in amu) of NI3. Calculate the molar mass of C u S O 4 5 H ...
To determine the density of an irregularly shaped object, a student immersed the object in 21.2milliliters of water in a graduated cylinder, causing the level of the water to rise to 27.8milliliters. If the object had a mass of 22.4grams, what was the density of the object? [Show all...
my thoughts on this is that I find out the weight of either Cl or X in a certain amount of the substance and from this this a ratio can easily be determined. so if i got 10 g of the substance and knew that 6 grams of it was Cl, through a test, then i could determine that X...
