The mass is 27,576 g.
0.0845 moles of tungsten is equal to 0,50887.10e23.
In order to figure this out, you must do dimensional analysis. Here it is: 3.0 moles He x 4.0026 grams/ mole He = 12 grams
The mass of sulfuric acid is 490,395 grams.
5,82 x 1023 atoms of tungsten equal 0,966 moles.
1 mole of oxygen weighs 16 grams. So, 1.8 moles would weigh 1.8 x 16 = 28.8g
1 mole weighs 183.54 g. So, 3.95 moles will weigh 724.983 g
16 grams of oxygen how many moles is 0,5 moles.
Need total molar mass sodium hydroxide which you can easily get from your periodic table. 2.2 moles NaOH (39.998 grams/1 mole NaOH) = 88 grams in mass ==============
To find the mass, we divide by Avogadro's number to find the amount of moles. We then multiply the moles by the molar mass of the compound which is 60.08 grams. Doing all of this, we get a mass in grams of 5.59 grams.
.75 moles times 64 grams/mols = 48 grams
53 grams ÷ 18.01 grams/mole = 2.94 moles
180 grams of water is 10 moles of water.
