Answer:
mass = 58.944 g
Explanation:
Given data:
Number of moles of SO₂ = 0.921 mol
Mass of SO₂ = ?
Solution:
Formula:
Number of moles = mass/ molar mass
First of all we will calculate the molar mass.
SO₂ = 32 + 16×2 = 64 g/mol
Now we will put the values in formula.
Number of moles = mass/ molar mass
0.921 mol = mass /64 g/mol
mass = 0.921 mol × 64 g/mol
mass = 58.944 g
B ase from the reaction <span>cacn2 3 h2o → caco3 2 nh3, for every 1 mole of caco3 produced there 2 moles of nh3 being produced. to solved this, we must first convert the caco3 to moles.
mass nh3 = 187 g caco3 (1 mol caco3 / 100 g caco3 ) ( 2 mol nh3 / 1 mol caco3) ( 17 g nh3 / 1 mol nh3)
mass nh3 = 63.58 g nh3 is produced</span>
