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.
The angle of depression is equal to the angle of elevation, so use the sine ratio to find the angle. sine = opposite (the vertical drop) divided by the hypotenuse (the ski slope) sine = 100/250 = 2/5 or 0.4 sine-1(0.4) = 23.57817848 degrees which is about 24 degrees
.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.
100-250 or so
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%.
