Molar mass of (NH4)2SO4 is 132.14 g/mol, so
4.69 (g) / 132.14 (g/mol) = 0.0355 mol
Molecular mass of H2SO4= 98.1 grams
4.60 × 1024 molecules / (6.02 × 1023 molecules) = 7.64 moles H2SO4
The molecular mass of sulfur trioxide, SO3 is 32.1+3(16.0) = 80.1
Amount of SO3 = 4.0/80.1 = 0.0499mol
0.0499 moles of SO3 are in a 4.0g pure sample.
The answer is 0,0477 mol.
You need the concentration of the acid.

First find out how many grams in 1 mole:Nitrogen is 14.007 g/mol, Hydrogen is 1.0079 g/mol, and Chlorine is 35.453 g/molThere are 4 Hydrogen, so 14.007 + 4*(1.0079) + 35.453 = 53.4916 g/mol(50 g)/(53.4916 g/mol) = 0.9347 moles
3,80 g Zn have 0,058 moles.
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
The answer is 0,364 moles.
The answer is 0,253 moles.
4,35 moles of silver is equal to 469 g (0,469 kg).
First find out how many grams in 1 mole:Nitrogen is 14.007 g/mol, Hydrogen is 1.0079 g/mol, and Chlorine is 35.453 g/molThere are 4 Hydrogen, so 14.007 + 4*(1.0079) + 35.453 = 53.4916 g/mol(50 g)/(53.4916 g/mol) = 0.9347 moles
3,80 g Zn have 0,058 moles.
The formula is: number of moles = g Be/9,012.
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
The answer is 0,4 moles.
The answer is 0,364 moles.
The answer is 0,253 moles.
573,28 of g of AgCI is equivalent to 4 moles.
978 g calcium contain 24,4 moles.
14,84 g magnesium are equivalent to 0,61 moles.
67,4 g HCl is equivalent to 1,85 moles.
