Answer:
0.106 moles
Explanation:
weight of substance = 5.96 g
molar mass of KOH = 39 + 16 + 1
= 56 g
number of moles = weight of substance/ molar mass of substance
= 5.96/56
= 0.106 moles
Answer:
+2
Explanation:
Since O &F Are more electronegative than N,
F=-1
2F=-2
O=-2
also the compound is neutral,
then 2N+2F+O=0
2N-2-2=0
2N=+4
N=+2
Answer:
30g
Explanation:
According to this question, a sulfur-containing compound is said to contain 15 percent by mass of sulfur. This means that 15% of the total mass of the compound is the mass of sulfur in the compound.
The question further states that there is a total of 200g of the compound containing sulfur, this means that the mass of sulfur can be calculated this:
Mass of sulfur = 15% of 200g
15/100 × 200g
15 × 2
30g
Hence, there are 30g of sulfur in 200g of the sulfur containing compound.
