Potassium bromide is KBr, the Atomic Mass of this compound is ca. 119.1.
no.moles = mass/relitive molecular mass, so in this case that's 245/119.1 = 2.057 moles of KBr.

What is the pressure in ATM exerted by 25.0 grams of XeF6 in a 5 liter container at 25 degrees Celsius?
Use the Ideal Gas Law: PV=nRT (pressure times volume equals moles times the ideal gas constant of 0.082 times the Kelvin temperature.) First, convert 25 Celsius to Kelvin: 25+273=298. Next, find out how many moles is in 25.0g of XeF6: 1(Xe)+6(F)=1(131.3)+6(19)=245g/mol; 25g XeF6=0.102mol. Then, plug it all in and solve for the pressure, which is your unknown: P(5L)=0.102mol(0.082)(298kelvins) Simplify: 5P=2.4925, P=0.4985, or approximately 0.5 atm of pressure.
How many grams of carbohydrates in a normal 1500 diet?
Adults should get 45 percent to 65 percent of their calories from carbohydrates.So that works out to 170g to 245g per day.Unless you are on a low carb or good diet then you should eat much less.
What is the percent by mass of 35g of sodium chloride mixed with 245ml of water?
Calculate the mass of water (density: 1 g/ml) --> 245 ml * 1 g/ml = 245 g of water wt % = 35 g / (35g + 245g) * 100% = 12.5%
If a graduated cylinder has a mass of 200g when 26ml of a liquid is added and it rises to 245 g What is the density of the liquid?
The increase in mass is 45g (245g - 200g) due to the added liquid. This corresponds to a volume of 26ml because 1g/ml is the density of water (and marketed) liquids. Therefore, the density of the liquid is 45g / 26ml = 1.73 g/ml.
How much vitamin k is in a pumpkin?
Fresh pumpkin only has about 2.0 mcg of Vitamin K per cup (or 245g). However, the same serving of canned pumpkin has 39.2 mcg of Vitamin K. So, if you're on a Vitamin K restricted diet, go for the fresh pumpkin, and be careful of breads, pastries and pies that are made using canned pumpkin. It's hard to say how much is in a whole pumpkin just gotten from a garden or farm, because the different sizes and shapes of pumpkins mean different amounts of the vitamin in each.
