B should be 20 because only 1 oxygen goes into water
C is hydrogen because 2 hydrogens go into each water
Can't read anything beyond c
Answer:
84.27 g
Explanation:
<em>How many grams of hydrogen are in 10.45 moles of C₃H₈?</em>
Step 1: Calculate the moles of atoms of hydrogen
The molar ratio of C₃H₈ to H is 1:8.
10.45 mol C₃H₈ × 8 mol H/ 1mol C₃H₈ = 83.60 mol H
Step 2: Calculate the mass corresponding to 83.60 moles of hydrogen
The molar mass of hydrogen is 1.008 g/mol.
83.60 mol × 1.008 g/mol = 84.27 g
I think it’s B not quite sure ! Sorry
