1 mol = 197g therefore,
32 mol = 6306 grams
= 0.75 mol x 32 g.mol-1 = 24 g
Molar mass of CuSO4= 63.5 + 32 +4 x 16=63.5 + 96= 159.5g
16 grams or 32 grams, depending on what you're looking at.The mass of one mole of oxygen atoms is about 16 grams, but oxygen gas exists as a molecule (O2) so 1 mole of (O2) is 32 grams.
174 grams/mole. Looking at the Periodic Table: K is 39 grams/mole, S is 32 grams/mole, and O is 16 grams/mole.So: 2*39 + 1*32 + 4*16 = 174.
number of moles=mass/molar mass =5/(28+32) =0.83 mol
= 0.75 mol x 32 g.mol-1 = 24 g
32 g as Oxygen has an atomic mass of 16.
no of mol = mass/molar mass = 72/ (40+32+16x4) = 72/136 = 0.529 mol (3.s.f)
Molar mass of CuSO4= 63.5 + 32 +4 x 16=63.5 + 96= 159.5g
16 grams or 32 grams, depending on what you're looking at.The mass of one mole of oxygen atoms is about 16 grams, but oxygen gas exists as a molecule (O2) so 1 mole of (O2) is 32 grams.
70 g/mol
174 grams/mole. Looking at the Periodic Table: K is 39 grams/mole, S is 32 grams/mole, and O is 16 grams/mole.So: 2*39 + 1*32 + 4*16 = 174.
number of moles=mass/molar mass =5/(28+32) =0.83 mol
Atomic oxygen does not have a greater atomic mass than chlorine, nor does molecular oxygen. The atomic mass of chlorine is approximately 35 g/mol, while molecular (O2) oxygen has a molecular mass of 32 g/mol.
256.52 g mol-1since sulfur molecules are S8.
Sulfuric acid has a molecualr weight of 98 and so 2.5 moles would weigh 245 g
Anhydrous sodium sulfate has a molar mass of (23+23+32+16+16+16+16) = 142.
