Answer:
Therefore, the hardness of the water in mol/L is 0.00134 mol/L
Explanation:
100ppm = 0.1g/L
134ppm = 134 × 0.1/100 = 0.134 g/L
Concentration in mol/L = (Concentration in g/L)/(molar mass)
Molar mass of CaCO₃ = 100.1 g/mol
Concentration In mol/L = 0.134/100.1 = 0.00134 mol/L
Therefore, the hardness of the water in mol/L is 0.00134 mol/L

Answer:
Venus observation.
Explanation:
Galileo had learned regarding the heliocentric (Sun-centered) idea of Copernicus, and acknowledged it. However, the theory was proven by Galileo's observations of Venus. Galileo concluded that Venus should travel round the Sun, sometimes passing behind and then beyond, instead of directly rotating around the Earth.

Yes thats correct....becuase all of your weight is concentrated on a small area compared to the larger surface area of your feet!
is that what your question was?
Answer: B
