The total mass of a mixture of 25g of salt and 125g of water is simply the sum of the individual masses. Therefore, the total mass is 25g + 125g = 150g.
The answer is 675 calories.

density = mass/volume,so the density of your metal is:25/10 = 2.5g/cm3 (grams per cm cubed)
The object's density is 0.0625 g/cm3
The solubility of KI at 30°C is about 50g/100mL of water. Therefore, in 50mL of water, you can dissolve a maximum of 25g of KI at 30°C.
percentage = 500%% rate:= 125g/25g * 100%= 5 * 100%= 500%
Density is mass divided by volume. To calculate density, you need to know the volume that the mass of 25g occupies. If you have this information, you can divide the mass (25g) by the volume to find the density.
The parts per million (ppm) of solute in a solution can be determined using the formula: ppm = (mass of solute/mass of solution) x 1,000,000. In this case, the mass of sodium chloride is 25g and the mass of the solution is 200g (25g NaCl + 200g water = 225g). Therefore, the ppm of sodium chloride in the solution is (25g/225g) x 1,000,000 = 111,111 ppm.
Really easy: put more solute in the solvent than the solvent can hold.If you're trying to make a saline solution with sediment and water can hold 25g/liter of salt (I just picked a number, sorry), put 50g/liter of salt in the water. 25g will dissolve, the rest will sink to the bottom.
Phthalic acid will dissolve 18g of per 100mL of boiling water. (25g/18g) x 100mL = 138.89mL of boiling water is needed to dissolve 25g of phthalic acid.
Grams are mass. There's no calculation involved.
To calculate the mass of steam produced from 25g of water, we need to consider the phase change from liquid water to steam. The specific heat capacity of water is 4.18 J/g°C, and the heat of vaporization of water is 2260 J/g. By using the formula Q = mcΔT for the water and Q = mL for the phase change, where Q is the heat energy, m is the mass, c is the specific heat capacity, ΔT is the temperature change, and L is the heat of vaporization, we can determine the mass of steam produced.
The density of the object is 2.5 g/cm^3. Density is calculated by dividing mass by volume, so in this case, 25g ÷ 10cm^3 = 2.5 g/cm^3.
The density of the object is 2.5 g/cm³. This is calculated by dividing the mass (25g) by the volume (10 cm³).
25 grams of steam are in 25 grams of water.
Density = Mass/Volume so 25/48 = 0.520833... grams per ml
mass is 1,2359 grams volume is 1.839 ml
