How is the mass in grams of an element converted to the amount of moles?
The formula is number of moles = mass / molecular mass. So say we have 1 mole of water. We look at the periodic table and molecular mass is 1+1+16 = 18g/mol. 1 mole x 18g/mol is 18 grams.
What mass of water would a ton of calcium carbonate produce if it was fully reacted with hydrochloric acid?
CaCO3 + 2HCl -> CaCl2 + CO2 + H2O 1 tonne = 2000 lbs ( I guess this is what you mean ) 2000 lbs CaCO3 (454 grams/1 lb)(1 mole CaCO3/100.09 grams)(1 mole H2O/1 mole CaCO3)(18.016 grams/1 mole H2O) = 163438.1856 grams of water ---------------------------- 163438.1856 grams (1 lb/454 grams) = 360 pounds of water -------------------------------
What is the mass of 1 mole aluminum?
26.98 grams
How many grams in one mole of silicon?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Selenium's atomic mass is 78.96 grams.
How is a mole related to the atomic mass?
The atomic mass, in grams, is the mass of one mole of atoms.
What is the mass of 1 mole of H2?
Mass and the number of mole in a given sample are related quickly with the equation #MOLE = MASS/MOLAR MASS Where the mass is in grams. Now, we know that the number of mole is one, and the molar mass can be found with any periodic table - 1.00794 abouts. Now, the equation reads 1 = MASS/1.00794 This can be rearranged through simple mathematics into 1*1.00794 = MASS/1.00794 * 1.00794 Or 1*1.00794 = MASS Since anything multiplied by one is itself, this can be simplified to 1.00794 = MASS So, the mass of 1 mole of Hydrogen is 1.00794 grams. Also, your question was a sentence :p
What is the mass of a half a mole of CO2?
1 mole CO2 has about 44 grams, so half a mole of CO2 equals 22 grams
What mass of oxygen in grams is in 147.2 grams of glucose?
147.2 grams C6H12O6 (1 mole C6H12O6/180.156 grams)(6 moles O/1 mole C6H12O6)(16.0 grams/1 mole O) = 78.4 grams oxygen ----------------------------
What is the weight of 0.8834 mole oxygen gas?
Oxygen has a molar mass of 16 grams per mole 1 mole = 16 grams 0.8834 mole = x grams x=14.1344 grams
What is the number of moles in 54 grams of aluminum?
For this you need the atomic mass of Al. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.54.0 grams Al / (27.0 grams) = 2.00 moles Al
How many grams o are there in 18 grams of water?
18 grams of water is 1 mole water. Water is H2O. That means there's 2 moles H and 1 Mole O. We're looking for "O", and there's one 1. So find the molar mass of O. (which is approx. 16) so 16 * 1 = 16.
What is the molar mass of 1-cyanopropane?
69.11 grams/mole
