Answer:
The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Molarity of solution is the ratio of the number of moles of the substance to the volume.
n is the number of moles of the compound
Mass of calcium nitrate = 54.3g
Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol
Get the required molarity;
Hence the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M

The climate controls that best explains the difference in average daytime temperature variation from month to month between Seattle and Fargo as well as between Dublin and Moscow is latitude
- Latitude is simply known as the highest force behind differences in temperature which also are fluctuations in incoming solar radiation. It alters (change) the angle of the sun and length of daylight control of the global distribution of temperature.
-
The 2 factors that causes this alterations or changes in latitude are therefore sun angle and length of daylight.
- Latitudes is known to show how much of the changes or variation in average temperature at a fixed latitude, average daytime temperature variation and seasonal fluctuations in temperature.
Conclusively, we can say that The climate controls that best explains the difference in average daytime temperature variation from month to month between Seattle and Fargo as well as between Dublin and Moscow is latitude
