Answer: 625 grams
Explanation:
14 goes into 56, 4 times.
10,000÷2=5,000 - first half life
5,000÷2=2,500 - second half life
2,500÷2=1,250 - 3rd half life
1,250÷2= 625 - 4th half life
Note: don't type "grams" after 625, just type "625".
Given:
2.5 mol O2
Required:
Grams of water
Solution:
2H2 + O2 -> 2H2O
Moles of H2O = (2.5 mol O2)(2 moles H2O/1 mole O2) = 5 moles H2O
Molar mass of H2O = 18.02 g/mol
Mass of H2O = (5 moles H2O)( 18.02 g/mol)
Mass of H2O =90.1g H2O
