Question 6 15 15 ncorrect Map sapling earning In a chemical reaction, exactly 2 mol of substance A react to produce exactly 3 mol of substance B. A 3 B How many molecules of substance B are produced when 28.0 g of substance A reacts? The molar mass of substance A is 17.2 g/mol. Step 1: Convert the mass of A to moles Number mol A 1.6 Step 2: Convert the number of moles of A to the number of moles of B Number 1.1 mol B Step 3: Convert the number of moles of B to molecules of B Number 23 molecules of B 6.5 x 10 A Previous Give Up & View Solution Check Answer Next I Exit 8 Hint

Explanation / Answer

2A ------ 3B

28g A

MW (A)= 17,2g/mol

Step 1:

28gA/17,2g/mol= 1,63mole A

Step 2:

2mole ---- reacts with---- 3moleB

1,63mole A ----------------   X = 2,45mole B

Step3:

1mol B ------ 6,02*10^23molecules B

2,45mole B ------X =1,47*10^24 molecules
