I don’t know what is your problem
Answer:
In my opinion B is the best answer
Explanation:
Answer:
2.74 percent hydrogen and 97.3 percent chlorine are in 2 g of compound.
The same as initial
Explanation:
HCl → H⁺ + Cl⁻
2.74% H means that in 100 g of compund, 2.74 grams are H
97.3 % Cl means that in 100 g of compound, 97.3 grams are Cl
So how many grams of H and Cl, are in 1 g of compound
100 g ___ 2.74 g are H _____ 97.3 g are Cl
1g _____ 2.74/100 ____ 97.3/100
0.0274 g are H
0.973 g are Cl
In 2 grams we will find
0.0274 g .2 = 0.0548 g of H
0.973 g .2 = 1.946 g of Cl
(grams / total grams) . 100 = %
(0.0548/2 ) .100 = 2.74%
(1.946 /2) .100 = 97.3%
