Answer:
236.8 g
Explanation:
From the reaction equation;
CaC2 + 2H2O(I) --------> C2H2(g) + Ca(OH)2(aq)
Since;
1 mole of CaC2 yields 1 mole of Ca(OH)2
It follows that 3.20 moles of CaC2 also yields 3.2 moles of Ca(OH)2
Mass of Ca(OH)2 = number of moles * molar mass
molar mass of Ca(OH)2 = 74 g/mol
Mass of Ca(OH)2 = 3.20 moles * 74 g/mol =
Mass of Ca(OH)2 = 236.8 g
Answer:
45
Explanation:
There are 12 Carbons
There are 22 Hydrogens
There are 11 Oxygens.
I think the answer is either 0 or 45. But the wording is very sloppy. It is not really atoms that are present. There are ions.
Go with 45 but hold your nose when writing your answer.
