Explanation:
I think 20
0 in the photo should be 1, 1, 1
Answer:
n=N/NA
n= 3.754×10²³/6.02×10²³
n= 6.24 s
Explanation
since there is number of molecules, make use of Avogadro's constant to get number of moles.
Answer:
<h2>D) 6</h2>
Explanation:
since, n = molar mass / empirical formula mass
Empirical formula mass = Total mass of atoms present in empirical formula
CHCl = 12+1+35.5
= 48.5
Given, Molar mass = 290.8 g.
So, n = 290.8/48.5
= 5.995 , that is approx 6.
So, Molecular formula = n × Empirical formula
= 6 × CHCl
= 
So, Number of C = 6
Answer:
112.18 g.
Explanation:
you're using stoichiometry to find the mass of the compound S₃O.
