Find the number of centimeters in 1.00 × 10^2 yards

Answer : The number in centimeter is, 9144 cm.

Explanation :

The conversion used from yard to centimeter is:

1 yard = 91.44 centimeter

As we are given the number yards. Now we have to determine the number in centimeter.

As, 1 yard = 91.44 centimeter

So, yard =

Therefore, the number in centimeter is 9144 cm.

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%
