The correct Answer is:B To calculate the percentage of water of crystallization in Blue Vitriol, CuSO4⋅5H2O, we will follow these steps: Step 1: Calculate the molar mass of CuSO4⋅5H2O 1. Calculate the molar mass of CuSO4: - Copper (Cu): 63.5g/mol - Sulfur (S): 32g/mol - Oxy...
Determine the equation for the streamline passing through the point (2 m, 3 m). How to calculate stagnation stream? Determine the critical depth for a flow of 200 m /s through a rectangular channel of 10-m width. If the water depth is 3.8 m, is the flow supercr...
Instead of grams, you need to convert into mol. This requires use of the molar heat capacity formula. That means you need the specific heat of water and the molar mass of water. The molar mass of water is 18.0 g/mol. molarheatcapacity=(4.18Jmol∗K)(18.0g1mol) Multiplying that toge...

Re: How do you calculate the molar mass? « Reply #1 on: February 18, 2008, 01:11:37 PM » Mikey, I will say that 8H2O is part of the composition and you should threat like that! the rest of the calculations is yours, I can write the whole process but the rules says that ...
Say you need to make a solution of 1M NaCl for a reaction you are running. How would you know how much salt to weigh out and then add to a given volume of water? To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that comp...
Calculate the heat of vaporization of an unknown substance X if 25 grams of X absorbs 1250 calories of heat when changing from a liquid to a gas. The molar mass of X is 100 g/mol. Calculate the energy needed to heat 14.3 grams of ice at ...
This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof thesolutefirst. To convert grams to moles, the molar mass of the solute is needed, which can be found on certainperiodic tables. ...
Calculate the volume and mass required to make 0.1M solutions of Ammonium Chloride (53.49gmol) and Ammonia (1.0M) Molarity: The molarity is always defined as the number of moles of solute that are dissolved in 1 liter of the solvent. If 1 mole of...
