NO such thing as 250% . 100% is totality!!!! However, 250 = 100 x 2.5 So multiply 1250 x 2.5 = 3125 The Answer!!!! NB It is a common mistake to say/write a percentage value greater than 100% . 100% is totality!!!!! What is meant is a value is multiplied by the increase.
275 and 250 = 275 + 250 = 525 exactly.
To determine percentages less than 100, multiply the number by x/100. The same holds for percentages over 100 - for example, finding 250 percent of a number is equivalent to multiplying the number by 250/100, that is, 2.5.
25% ammonia solution means 25g Ammonia in 100ml of water. To convert it into moles i.e for 1000ml solvent, 25x100=250 which means 250g of ammonia is present in 1000ml of water to make a 25%solution. To convert it into molar solution we will divide 250 by the molecular mass of ammonia i.e 17. 250/17= 14.71M This means that 25% ammonia solution contains 14.71 moles of ammonia. Now we will use the formula M1V1=M2V2 Let's say we want to make 10 molar solution in 500ml water. Then, M1=14.71 V1=? M2=10 V2=500 Putting values in the above equation: 14.71xV1 = 10x500 V1 = 10x500 / 14.71 = 340ml We will take 340ml of the 25% ammonia solution and make the volume up to 500ml with water. This will be our 10 molar solution of Ammonia.
if 044. --> 44/1 if 4.40 --> 22/5if 0.44 --> 44/100 = 11/25if .044 --> 44/1000 = 11/250
.025 percent Solution Method: 250 ppm = the ratio 250:1,000,000 = the fraction 250/1,000,000 = the decimal value 0.00025 = the percentage .025 (i.e. 0.00025 * 100)
% change = 150%% change=|original value - new value|/original value * 100%=|100 - 250|/100 * 100%=150/1 * 1%= 150%

To find the grams in 250 ml of a 5% solution, you can use the formula: (volume in ml * percentage concentration / 100). So for this case: (250 ml * 5%/100) = 12.5 grams.

Mass percent of calcium chloride in the solution is calculated as (mass of calcium chloride / total mass of solution) * 100. In this case, it would be (30 g / (30 g + 250 g)) * 100 = 10.7%.
