What is the molarity of 80g magnesium chloride dissolved in 250ml of water?
EmmaHendry
MgCl2
Molarity = moles of solute/Liters of solution ( 250 ml = 0.250 L )
Get moles MgCl2
80 grams MgCl2 (1 mole MgCl2/95.21 grams)
= 0.8402 moles MgCl2
Molarity = 0.8402 moles MgCl2/0.250 Liters
= 3.4 M MgCl2

What is the molarity of 25.0 mL of 3.50 M HNO3 diluted to 0.250L?
30 ml diluted to 250ml. 3.5 molar divided by 250 is 0.014. This multiplied by 30 is 0.42 molar.
How many grams of calcium chloride will you add to 250mL of water to make a 0.236 M solution?
Molarity is moles of solute / liters of solvent. Plugging in the data: 0.236M = x / 0.250L; x = (0.236M)(0.250L) = 0.0590 moles of CaCl2. The molecular weight of CaCl2 is 40.1 + 2(35.5) = 111.1 g / mole. The mass of CaCl2 = (MW)(moles) = (111.1g/mole)(0.0590moles) = 6.55g
If 250ml of solution contains 42g of Magnesium nitrate calculate the concentration of nitrate ions?

What is made by adding 4.5 moles of NH3 to 250ml of water.what is the molarity?
Well molarity means moles per litre. So here, you need to multiply by 4 as 250x4 is a litre. 4.5*4 is 18 molar.
When you add 5ml of sugar to 250ml of coffee the volume is still 250ml?
When sugar is dissolved in coffee, the sugar molecules is fitted inside the empty spaces in the water molecules. This means that the volume of coffee does not increase.
If 6.73g of Na2CO3 is dissolved in enough water to make 250ml of solution what is the molarity of the sodium carbonate what are the molar concentrations of the Na plus and CO32- ions?
6.73g (1 mole of Na2CO3/106g) = 0.063mol/0.25L = 0.25M Na2CO3 2 moles of Na+ x 0.25M = 0.5M Na+ 1 mole of CO32- x 0.25M = 0.25M CO3
