O
Molecular mass of H
2
=2 g/mol
Molecular mass of O
2
=32 g/mol
From the balanced chemical equation,
2×2=4 g of hydrogen requires 32 g of Oxygen to react completely
Density of liquid= 
.
so, density of liquid= 
= 1.2 gm/cm³.
Answer:
1,806,000,000,000,000,000,000,000 atoms.
Explanation:
1 mol of anything is 6.022*10^23 units
1 mol carbon atoms = 6.022*10^23 carbon atoms
3 mol carbon atoms = 3*6.022*10^23 = 1.8*10^24 atoms
Correctly - your answer should have only 1 significant digit: 2 * 10^24 atoms.
