What is the molarity of 200 ml of solution which 2.0 moles of sodium bromide is dissolved?
So molarity means moles per litre. but you don't have a litre. if you did you'd have 1000/200 times the moles that you have. 2 moles / 200 x 1000 is 10 moles. As it is per litre, it is 2 molar.
How many moles of sodium chloride are in 200 ml of a 6M solution?
200/1000 x 6 = 1.2 moles
How many moles of sucrose are in 200 grams?
200g times 342.2965 g/mol = 68459.3 moles
How many moles of CH4 are in 200 grams of CH4?
200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4
What is the molarity of a solution with 5 moles of lithium flouride dissolved in 200 mL of water?
Molarity is per litre. Therefore 200x5 is a litre. so 5x5 is 25. The answer is 25 molar.

How many moles in 200 grams of calcium?
5
How many moles of sucrose are in 200 grams?
200g times 342.2965 g/mol = 68459.3 moles
How many moles in 1 g of zinc nitrate?
200
How many moles of CH4 are in 200 grams of CH4?
200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4
How many moles are in 1200 grams of calcium bromide?
The molecular weight of Calcium Bromide is extremely close to 200. So 1200/200 = 6 moles present.
What is the molarity of a solution with 5 moles of lithium flouride dissolved in 200 mL of water?
Molarity is per litre. Therefore 200x5 is a litre. so 5x5 is 25. The answer is 25 molar.
How many moles of Cu were in the original sample which had been effectively diluted to a volume of 200 m?
(0.102gx1mole)/99g CuCl = 1.031x10^-3 moles
How many moles of HCl are present in 75 mL of a 200 M solution?
.0150 mol
How many moles of solute are contained in 200 milliliters of 1 M solution?
200 mL is 0.200 L and 0.90 M means 0.90 moles/L So, 0.200 L x 0.90 moles/L = 0.18 moles
How many moles of MgCl2 are present in 90.0 mL of 0.200 M MgCl2 solution?
You have 2 litres. You need to divide 91 by 2 to get it per litre. 91/2 is 45.5g. 45.5 / 95.211. This gives you 0.477886 molar
