An 18.5 g sample of tin (molar mass = 118.7) combines with
1 answer:
Answer:
Option (B) SnS2
Explanation:
Data obtained from the question include:
Mass of Sn = 18.5 g
Mass of S = 10 g
The empirical formula of the compound can be obtained by doing the following:
Step 1:
Divide each element by their molar mass
Sn = 18.5/ 118.7 = 0.156
S = 10/ 32.07 = 0.312
Step 2:
Divide each by the smallest number
Sn = 0.156/0.156 = 1
S = 0.312/0.156 = 2
The empirical formula is SnS2

Answer:
8.96 L
Explanation:
At STP, 1 mole = 22.4 L
0.400 mole * (22.4 L. /1 mole of gas) = 8.96 L
