1. Four bicyclists travel different distances and times along a straight path. 1 poir Which cyclist traveled with the greatest average speed? *
Cyclist 1 travels 95 m in 27 s
O Cyclist 2 travels 87 m in 22 s
O Cyclist 3 travels 106 m in 26 s
O Cyclist 4 travels 108 m in 24 s
2. Using the granh

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

we need the questions , i may then you.

there is none because earth is stationary and flat.
