Answer:
34.81 ×10²³ atoms
Explanation:
Given data:
Mass of water = 52.0 g
Number of atoms of hydrogen = ?
Solution:
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 52.0 g/ 18 g/mol
Number of moles = 2.89 mol
1 mole of water contain 2 mole of hydrogen.
2.89 mole of water contain 2.89× 2= 5.78 moles of hydrogen.
Number of atoms of hydrogen:
1 mole = 6.022×10²³ atoms
5.78 mol × 6.022×10²³ atoms / 1mol
34.81 ×10²³ atoms

Answer:
10.875 miles
So 87 minutes
.125 miles per minute
So just multiply int his case
87*.125
You’d get 10.875
