NOT MY WORDS TAKEN FROM A SOURCE!!!!
Any naturally occurring homogeneous solid that has a definite (but not fixed) chemical composition and a distinctive internal crystal structure.
Minerals are usually formed by inorganic processes.
Synthetic equivalents of various minerals, such as emeralds and diamonds, are manufactured for commercial purposes.
Although most minerals are chemical compounds, a small number (e.g., sulfur, copper, gold) are elements.
Minerals combine with each other to form rocks.
For example, granite consists of the minerals feldspar, quartz, mica, and amphibole in varying amounts.
Rocks are generally, therefore, an intergrowth of various minerals.<span> </span>

Answer:
10.6%
Explanation:
The determined percent mass of water can be calculated from the formula of the hydrate by
dividing the mass of water in one mole of the hydrate by the molar mass of the hydrate and
multiplying this fraction by 100.
Manganese(ii) sulphate monohydrate is MnSO4 . H2O
1. Calculate the formula mass. When determining the formula mass for a hydrate, the waters of
hydration must be included.
1 Manganes 52.94 g = 63.55 g
1 Sulphur 32.07 g =
32.07 g 2 Hydrogen is = 2.02 g
4 Oygen =
64.00 g 1 Oxygen 16.00 = 16.00 g
151.01 g/mol 18.02 g/mol
Formula Mass = 151.01 + (18.02) = 169.03 g/mol
2. Divide the mass of water in one mole of the hydrate by the molar mass of the hydrate and
multiply this fraction by 100.
Percent hydration = (18.02 g /169.03 g) x (100) = 10.6%
The final result is 10.6% after the two steps calculations
