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.
moles = 245g / atomic weight of gallium = 245 / 69.72 = 3.51 moles
1 mole Si = 28.0855g Si 245g Si x 1mol Si/28.0855g Si = 8.72 moles Si
40,186 lots of 245g in 10,000kg.
There is exactly 100 in a 245g bag

Buttermilk contains 5g of fat per 245g serving (approximately 1 glass) This is 8% of your RDA It also contains 3g of saturated fat per 245g serving This is 15% of your RDA
Answer: 245 lb = 111,130.130 g
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.
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.
285C is above the boiling point of water at standard pressure. The block of copper will flash the water to steam, and the results of the experiment will be invalid.
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%
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.
