There are two steps to solving this problem:
Step 1: Calculate the molar mass of KBr (molar mass is the amount, in grams, that one mole of a substance weighs).
From the Periodic Table, we see that the molar mass of K is 39.10 g/mol (its average Atomic Mass). Similarly, the molar mass of Br is 79.90 g/mol. Adding these numbers together gives the molar mass of KBr, 119 g/mol.
Step 2: Calculate the weight, in grams, using the molar mass and the number of moles.
For every one mole of KBr, you have 119 grams of KBr:
mass (m) = 119 g/mol * 3.30 mol
mass (m) = 392.7 g
Therefore, 3.30 moles of KBr weighs approximately 392.7 grams.

What is the molarity of a CaCl2 solution containing 330 grams of CaCl2 in 1 liter of solution?
First, calculate the molar mass of CaCl2, which is 110.98 g/mol. Next, calculate the number of moles of CaCl2 in 330 grams using the formula moles = mass / molar mass. This gives you 2.97 mol of CaCl2. Finally, divide the moles of CaCl2 by the volume of the solution in liters to get the molarity, which is 2.97 M.
What is the mass in grams of 8.23 moles of Ca?
For this you need the atomic (molecular) mass of CaH2. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. CaH2=42.1 grams1.72 moles CaH2 × (42.1 grams) =72.4 grams CaH2
How many grams of KNO3 will dissolve in 100 g of water at 30 degrees Celsius?
Instead of waiting for the answer, I ended up solving it. lol 300grams of H20 X 110grams of KNO3/100 grams of H20 = 330 grams of KNO3 The grams of H20 both cancel out and leave you with 330 grams of KNO3 Containing the solubility of KNO3. At 60 degrees celsius the KNO3 grams were 110, which is (over) / 100grams of H20. Hope this helps with this workbook problem :)
How many sugar cubes are in pepsi?

How much energy is needed to vaporize 2 kg of gold?
The energy required to vaporize a material can be calculated using its heat of vaporization. For gold, the heat of vaporization is approximately 330 kJ/mol. Since gold has a molar mass of 196.97 g/mol, 2 kg of gold is equal to 10.15 moles. Therefore, the energy needed to vaporize 2 kg of gold is approximately 3.35 MJ.

How many grams are contained in 168 l of CO2 at stp?
At standard temperature and pressure (STP), 1 mole of any ideal gas occupies 22.4 liters. To find the number of moles in 168 liters of CO2, you can divide 168 by 22.4, which gives approximately 7.5 moles. Since the molar mass of CO2 is about 44 grams per mole, you can multiply 7.5 moles by 44 grams/mole to find that 168 liters of CO2 contains approximately 330 grams.
