2.,7 moles of glucose have 486,432 g.
There are 1.5 moles water in 27 grams
There is 19g of fluorine. That makes 1 mole.
One mole weights 26.98 grams, so it is arouind 27 g. So 4 moles weight almost 108 grams.
About 907.2 grams.
The approximate molar mass of Al(OH)3 = 27 + 48 + 3 = 78 g/mol150 g x 1 mol/78 g = 1.92 moles
(2.7 mol Ca / 1) * (40.078 g Ca / 1 mol Ca) = 108.21 g Ca. After significant figures, the answer is 110 g Ca.
The formular you need is M = n/m (molar mass = amount of substance/mass), or n = m/MAluminium has a molar mass of 26.982 g/mol. The given mass is 3 grams. Therefore:n(Al) = 3g / (26.982g/mol) = 0.11mol
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58 grams 25.0 grams NaCl / (58 grams) = .431* moles NaCl *approximation
For this you need the atomic mass of Al. Take the number of grams and divide it by the atomic mass. Multiply it by one mole for units to cancel.94.5 grams Al / (27.0 grams) = 3.50 moles Al
For this you need the atomic mass of Al. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.2.00 moles Al × (27.0 grams) = 54.0 grams Al
The number of grams of Aluminum in one mole of Aluminum is the number under the element's symbol, on the periodic table of the elements, which is 26.981. With compounds, water, for example, is an oxygen and two hydrogens. So you would add 15.999 to 2(1.0079). You multiply the hydrogen's number by two because there's two of them.
